Structure and optical properties of TeO2 center dot PbCl2 center dot PbF2 glasses doped with Pr and Er, prepared in Au or Pt crucibles
Original language description
Influence of crucibles (Au or Pt) on the structure and optical properties of 60TeO(2)center dot 40PbCl(2) and 60TeO(2)center dot 20PbCl(2)center dot 20PbF(2) glasses, "pure" and doped with 1000 wt-ppm Pr3+ or Er3+, which are added as metals, chlorides, or oxides, is reported. In glasses prepared in Au crucibles, the absorption edge is shifted to shorter wavelengths and the color of the glass is changed from red or orange to yellowish or dirty white, respectively. In the range of 640-700 nm, five Pr or six Er photoluminescence (PL) peaks are observed. In the range of 200 - 1200 cm(-1), Raman scattering (RS) spectrums show 6 (for Pr doping) or 7 (for Er doping) bands. Spectrums are deconvoluted using symmetrical Gaussian functions. Relative intensities of PL and RS peaks depend on the chemical form of dopants and on the material of the crucible. Positions of these bands are almost independent of these conditions. On basis of RS spectrums, short-distance ordering of glasses is discussed.
