Environmental Radiation Monitoring Using Radiophotoluminescence in Silver-Doped Phosphate Glass
Procedia Engineering, 2020Co-Authors: Hidehito Nanto, Yuka Miyamoto, Yoshinori Takei, Toshio Kurobori, T. Oono, Takayoshi YamamotoAbstract:Abstract Optical properties such as optical absorption and radiophotoluminescence (RPL) spectra of silver (Ag + )-doped Phosphate Glass before and after x-ray irradiation were investigated in this study. It is found that the RPL spectrum consists of two emission bands which are peaked at 2.70 eV (460 nm blue emission) and 2.21 eV (560 nm yellow emission). It is also found that RPL emission intensity gradually increases with x-ray irradiation dose. From the results it is suggested that origin of each 460 nm and 560 nm RPL emission band is ascribed to Ag 0 ion and Ag 2+ ion, respectively, which are produced by x-ray irradiation. The application of the RPL phenomenon in Ag-doped Phosphate Glass to the environmental natural radiation monitoring is also demonstrated. © 2011 Published by Elsevier Ltd.

Radiation Measurements, 2014Co-Authors: Yuka Miyamoto, Hidehito Nanto, Toshio Kurobori, Takayuki Yanagida, Yutaka Fujimoto, Jumpei Ueda, Setsuhisa Tanabe, Takayoshi YamamotoAbstract:Abstract The objective of this study is to investigate the emission mechanism of radiophotoluminescence (RPL) in the Ag + -doped Phosphate Glass (Glass dosimeter), which is now used as individual radiation dosimeter, because the emission mechanism of RPL in Glass dosimeter has been not fully understood. We have investigated the assignments and characteristics of the X-ray induced color centers in the Ag + -doped Phosphate Glass up to now ( Miyamoto et al., 2010 ). Optical properties such as optical absorption spectra related with alpha-particles and X-rays irradiation were measured for commercially available Glass dosimeter. In this study optical properties such as optical absorption spectrum as a function of alpha-particles and X-rays irradiation were measured for commercially available Glass dosimeter.

A novel ionizing radiation sensor utilizing radiophotoluminescence in silver-doped Phosphate Glass
Proceedings of SPIE, 2014Co-Authors: Hidehito Nanto, Yuka Miyamoto, Yoshinori Takei, Toshio Kurobori, Takayoshi Yamamoto, T. Ohno, T. Ikeguchi, Kazuki Hirasawa, T. IidaAbstract:Silver (Ag + ) doped Phosphate Glass exhibits an intense photoluminescence (PL) when the non-irradiated Ag + -doped Phosphate Glass is excited with about 230 nm ultra-violet light. In x-ray irradiated Glass, intense radiophotoluminescense (RPL) is observed when the irradiated Glass is excited with about 340 nm ultra-violet light. It is found that the RPL spectrum includes two emission bands such as blue emission band peaked at about 460 nm (lifetime: about 6.6 ns) and yellow RPL emission band peaked at about 560 nm (lifetime : about 2.2μs). The PL intensity is decreased with increasing x-ray irradiation dose, while the RPL intensity is increased with x-ray absorbed dose. For the annealing of x-ray irradiated Glass at 523 K, the RPL intensity is decreased with annealing, while the PL intensity is increased with annealing. The RPL is vanished and the PL is recovered at original intensity by annealing at 523 K for 40 min. This means that there is a complementary relationship between the PL and RPL on irradiation and heat-treatment processes. The RPL intensity is increased with increasing the x-ray absorbed dose in the range from 0.01 mGy to about 20 Gy, showing that the Ag + -doped Phosphate Glass can be useful for individual radiation monitoring and environmental radiation monitoring. On the basis of such potentiality of Glass as the dosimeter, the application of Ag + -doped Phosphate Glass on environmental radiation monitoring is discussed and the RPL response of the Glass for α- particle and heavy-particle (He, C, Fe particle) irradiation is demonstrated.

Investigation on thermal properties of a new Nd-doped Phosphate Glass
Ceramics International, 2014Co-Authors: Weiwei Li, Wei Chen, Dongbing He, Shunguang Li, Lili HuAbstract:Abstract Thermal properties of a new Nd-doped Phosphate Glass were investigated. The thermal expansion coefficient was measured by a dilatometric technique. A Mach–Zehnder interferometer was used to measure the temperature coefficient of refractive index (d n /d T ) and the thermo-optic coefficient (d s /d T ) in the temperature range of 30–100 °C. A low thermal expansion coefficient was observed for the new Phosphate Glass. The dispersion of the thermo-optic parameters was calculated from an empirical equation. The thermo-optic coefficient (d s /d T ) at the working wavelength of 1053 nm is lower than those of other high average power Glasses. These results indicate that the new Nd-doped Phosphate Glass is a good candidate for high average power laser applications.

Experimental investigation on laser-induced surface damage threshold of Nd-doped Phosphate Glass
Chinese Optics Letters, 2012Co-Authors: Junjiang Hu, Lei Zhang, Wei Chen, Changhe Zhou, Lili HuAbstract:Nd-doped Phosphate Glass is the dominant amplifier material used in solid state high average power laser systems. Surface imperfection and subsurface damage (SSD) of the Glass, resulting from the optical fabrication process, limit the increment of laser system energy output. Thus, it is important to enhance the surface damage threshold of Nd-doped Phosphate Glass surface. The in°uence of abrasive size, polishing powder, grinding mode, and chemical treatment on the laser-induced damage threshold (LIDT) of Nd-doped Phosphate Glass surface is investigated. Results show that the LIDT is affected little by different polishing powders and grinding modes. The LIDT correlates with the abrasive size, which produced different depths of SSD. A suitable acid etching treatment can remove the imperfection and the SSD for improving the LIDT of Nd-doped Phosphate Glass surface. The combination of several effective techniques and methods, which are low-cost and practical, should be useful to enhance the LIDT of Nd-doped Phosphate Glass surface.
