Optical Absorption Processes in CdSe Nanocrystals Embedded in Silicate Glass and Organic Polymer Matrices Under 7-MeV Electron Irradiation
Abstract:Irradiation-induced bleaching occurs in the spectra of glass-embedded CdSe nanocrystals due to their ionization resulting from charge transfer between them and color centers formed in glass by electron irradiation. No bleaching in the spectra of CdSe nanocrystals encapsulated in gelatine is observed because no deep traps are formed in the matrix under electron irradiation.
