Abstract

In this paper, optical glass nanocomposites (nanoparticles sizes up to 100 nm) with composition TeO ₂-WO ₃-PbO-xEr ₂O ₃-yPr ₆O ₁₁ (x = 0.30 mol%, y = 0.70 mol%) embedded into polymer matrices was reported. The two types of polymers chosen for present study were: photopolymer oligoetheracryalte (OEA) and polymethylmethacrylate (PMMA), respectively. The incorporation of the titled nanoparticles into the polymer matrices is analyzed optically. The fluorescence spectra of the nanocomposites were compared with the fluorescence spectra of bulk glasses. Based on the comparison of Er ^{3 +} and Pr ^{3 +} ions' energy level schemes, possible energy transfer processes were identified. The prepared glasses are promising candidates for the white light emitting diodes applications.
