Description
| - Homogeneous glasses of the system 80GeSe(2) center dot (20-x)Sb2Se3 center dot xSb(2)Te(y):0.03Pr(2)Se(3) glasses; x=0, 1, 3, 10; y=2, 3, 4 were prepared. The glasses with x=0-3 are very stable without any crystallization for T { 600 degrees C. The T-g values (261-309 degrees C) and the E-g(opt) values (1.30-1.70 eV) are decreasing with the Te content. The index of refraction is high (2.55-2.73 for 2200 nm), it is increasing with increasing Te content. The Raman spectra revealed presence of GeSe4/2 tetrahedra, Ge2Se6/2 bi-tetrahedra and SbSe3/2 trigonal pyramids in studied glasses. The tellurium atoms are forming SbSe2Te and SbSeTe2 distorted pyramids. The strong luminescence corresponding to 4f transitions in Pr3+ ions was found in spectral regions (1100-1450 nm, 1500-1700 nm, 1750-2000, 2000-2600 nm and 3600-5200 nm; lambda(exc)=980, 1050 and 1550 nm). The intensities of luminescence bands depend on their composition.
