vibrational structure of Luminiscence Spectrum of cr3 in mgal2o4
Physics and Chemistry of Minerals, 1993Co-Authors: Maria Czaja, Z MazurakAbstract:The optical absorption and luminescence spectra of MgAl2O4:Cr3+ natural spinel (from Ural) have been measured at 77 K and 293 K. The luminescent emission from 4T2g, 2Eg covers wide region of 600–750 nm. The emission Spectrum at 77 K shows a very rich vibrational structure which can be mainly explained through the vibrational modes of the oxygen octahedron.

Intensidades espectrales en compuestos de coordinación de los metales de transición: aplicaciones a sistemas del tipo Cs2SnBr6: OsBr26
Revista Mexicana De Fisica, 2009Co-Authors: Roberto Acevedo, G. Muñoz, T. MeruaneAbstract:EL ESPECTRO DE LUMINISCENCIA DEL SISTEMA CS-2 SNBR6:OSBR2-6 ES EXAMINADO UTILIZANDO UN FORMALISMO VIBRONICO GENERALIZADO. PARA EFECTOS ILUSTRATIVOS HEMOS ESCOGIDO LAS EXCITACIONES MAS CARACTERISTICAS, LAS CUALES EXHIBEN UNA RIQUISIMA ESTRUCTURA VIBRONICA Y DISTRIBUCIONES DE INTENSIDADES NO ESPERADAS. ESTAS ABSORCIONES SON ANALIZADAS CON ENFASIS EN LOS FACTORES ELECTRONICOS Y VIBRACIONALES QUE DETERMINAN LAS INTENSIDADES ESPECTRALES GLOBALES Y LAS DISTRIBUCIONES RELATIVAS DE INTENSIDADES ASOCIADAS A TRANSICIONES ELECTRONICAS GENERICAS DE LA FORMA TM = R-+ VK (K = 3,4,6). LAS BONDADES Y DESVENTAJAS DE LOS METODOS DE CALCULO COMO TAMBIEN UN ESTUDIO CRITICO DE LOS DATOS EXPERIMENTALES DISPONIBLES ES UNO DE LOS OBJETIVOS CENTRALES DE ESTE TRABAJO. CONCLUSIONES RELEVANTES CON RELACION A LOS MECANISMOS DE INTENSIDADES ESPECTRALES COMO TAMBIEN A ACOPLAMIENTOS DE VIBRACIONES INTERNAS Y EXTERNAS SON OBTENIDAS Y SUGERIDAS PARA MEJORAR NUESTRA COMPRENSION DE ESTOS COMPLEJOS PROCESOS. Abstract THE Luminiscence Spectrum OF THE CS2SNBR6:OSBR2-6 SYSTEM IS EXAMINED UTILIZING A GENERALIZED VIBRONIC FORMALISMS. FOR ILLUSTRATIVE PURPOSES WE HAVE CHOSEN THE MOST CHARACTERISTIC EXCITATIONS, WHICH SHOW UP A RICH AND UNEXPECTED VIBRONIC STRUCTURES. THESE ABSORPTIONS ARE TACKLED WITH EMPHASIS ON BOTH THE ELECTRONIC AND THE VIBRATIONAL FACTORS WHICH ARE RESPONSIBLE FOR BOTH THE OVERALL AND THE RELA TIVE VIBRONIC INTENSITIES ASSOCIATED WITH GENERIC TRANSITIONS OF THE -M = -1 + VK (K = 3, 4, 6) TYPE. THE ADVANTAGES AND DISAVANTAGES OF THE CALCULATION MODEL AS WELL AS A CRITICAL STUDIES OF THE EXPERIMENTAL DATA AVAILABLE ARE DISCUSSED. RELEVANT CONCLUSIONS ARE DRAWN OUT IN CONECTION WITH THE INTENSITY SPECTRAL MECHANISM AS WELL AS THE EVENTUAL INFLUENCE ON THE CALCULATED INTENSITIES DUE TO THE COUPLING AMONG THE INTERNAL AND THE ESTERNAL VIBRATIONS AND SOME SUGGESTIONS FOR IMPROVEMENTS ARE PUT FORWARD TO ADVANCE THE STATE OF THE ART IN THE VIBRONIC COUPLING THEORY.
