X-Ray Excited Luminescence and X-Ray Irradiation Effect on CdS sub 1-x Se sub x Nanocrystals Optical Absorption

Abstract

X-ray excited luminescence and X-ray irradiation (10-3240 Gy) effect on the optical absorption spectra of CdS(1-x)Se(x) nanocrystals in borosilicate matrix are studied. The parameters of the luminescence bands are analyzed with the account of the luminescence of the host matrix it- self The observed smearing of quantum-size-related maxima and absorption edge blue shift with the irradiation dose increase are related to the X-ray ionization of the nanocrystals with charge-carrier transfer between the nanocrystals and the host matrix. The radiation-induced changes completely vanish at post-irradiation annealing to 575 K.
