چکیده انگلیسی
Fluorescence of 65GeS2-25Ga2S3-10CsCl glasses doped with Er has been investigated at room and liquid nitrogen temperatures. Strong emission lines at â¼1 and â¼1.5 μm are observed at room temperature in Er-doped samples when excited with â¼530 nm wavelength. At cryogenic temperature, this fluorescence is observed even at lower excitation wavelengths (â¼400-450 nm). The other observed emission and absorption lines agree well with known energy level transitions of Er3+ ions incorporated in the glass matrix and temperature behavior of absorption spectra. The difference between room and liquid nitrogen temperature up-conversion emission is observed under femtosecond pulsed 800 nm laser excitation.
