Influence of preparation technique and Pr3+ doping on the absorption edge, photoluminescence, and Raman spectra of 70TeO(2)center dot 30PbCl(2) glasses

Popis výsledku v původním jazyce

Tellurite glasses, 70TeO(2).30PbCl(2), were prepared in Au and Pt crucibles.Doping with Pr3+ and reactions with crucibles result in structural changes of tellurite polyhedrons. The influence of W on the local structure is similar to that of incorporatedAu+ from the crucible. Relative intensities of PL bands and RS ones depend on the concentration of Pr3+ and on the material of the crucible. Positions of these bands are independent of Pr3+ concentration and of the material of the crucible. The form, slope, and position of the absorption edge depend on the material of the crucible, and on the concentration and chemical form of Pr. Absorption edge of glasses prepared in Au crucibles is much sharper and shifted to shorter wave-length in comparison to thatof glasses prepared in Pt crucibles.
