Abstract

The glass samples with composition TeO 2-WO 3-PbO- xEr 2O 3-yPr 6O 11 (x = 0,30%mol, y = 0,07%mol) were synthesized and studied with respect to the light emitting features. These glasses possess high photothermal stability and resistance against crystallization during reheating. The observed fluorescent spectra cover a wide visible spectral range. Due to simultaneous presence of both Er 3+ and Pr 3+ ions in the glass, nearly all absorption peaks are strongly overlapping. Careful analysis of the emission spectra allowed to assign all the observed peaks. From comparison of the Er 3+ and Pr 3+ ions' energy level schemes, possible energy transfer processes were identified. The prepared glasses possess high quantum efficiency, which allow use them for white light emitting diodes.
