Luminescence Spectroscopy of Sn2P2S6 Crystals
Original language description
The emission and excitation spectra of luminescence of a Sn2P2S6 crystal were studied in detail within wide temperature (12 - 360 K) and spectral (260 - 1000 nm) regions. Illumination with monochromatic light with the wavelength shorter than about 710 nmat low temperatures enabled to observe broad-band photoluminescence in the red and near-infrared spectral regions. Analysis of the emission spectra revealed a superimposition of three overlapping bands of nearly Gaussian shape peaking near 1.75, 1.57, and 1.39 eV at 12 K. At steady-state excitation at 12 K, the changes of photoluminescence intensity were observed with time of crystal illumination. During subsequent heating of the crystal with a rate of 0.082 K/s weak thermoluminescence was observed within 15 - 130 K. The trap depths of 41 and 88 meV, corresponding to two pronounced glow peaks near 22 and 41 K, were determined by the "initial rise" method.
