  • structure and white Led properties of ce doped yag al2o3 eutectics grown by the micro pulling down method
    CrystEngComm, 2019
    Co-Authors: Qingsong Song, Xiaodong Xu, Xiangshai Bu, Dongzhen Li, Yinzhen Wang, Jun Xu, Kheirreddine Lebbou
    Abstract:

    A series of Ce-doped YAG-Al2O3 eutectics were grown by the micro-pulling-down (μ-PD) method, for the purpose of high power white light emitting diodes. The eutectic structure was investigated. A calibrated integrating sphere spectrometer setup was used to measure the white Led properties of eutectic samples. The CIE color coordinates can be regulated easily by altering the Ce3+ doping concentration and sample thickness of the Ce:YAG-Al2O3 eutectics. A 1 W white Led Device based on Ce:YAG-Al2O3 eutectics at a rated current of 350 mA emitted a bright white light with a CIE coordinate of (0.319, 0.334), a luminous efficacy of 83.0 lm W−1 and a Duv value of 0.003. The results showed that Ce:YAG-Al2O3 eutectics have better luminescence properties than commercial powder phosphors at a high current density.
