Rezumat

În lucrare sunt prezentate rezultatele studiului fotoluminescenţei (FL) cristalelor ZnSe:Cr. În spectrele de FL a cristalelor ZnSe:Cr au fost depistate benzi în regiunile albastră şi IR ale spectrului. Aceste benzi sunt determinate de tranziţiile ionizante de ionii Cr şi Cr în ZnSe. Se analizează mecanismele de excitare a FL şi mecanismele ce determină FL în regiunea IR a spectrului în ZnSe:Cr. Rezultatele pot fi folosite pentru pompajul optic al laserilor în baza ZnSe:Cr.

Results on photoluminescence (PL) of ZnSe:Cr crystals are reported. Blue and infrared emission were observed in ZnSe:Cr. These emissions are explained by 2 to 1 ionization transitions of chromium ions in ZnSe. The analysis of the mechanism of PL excitation and IR PL emission in ZnSe:Cr are discussed. The results of photoionization excitation mechanism can be applied for optical pumping of lasers based on ZnSe:Cr crystals.
