Description:
The authors report on the UV-excited photoluminescence measured in Sb 2 O 3 – ZnO – P 2 O 5 glass. Pre-heat treatment performed before melting effectively prevented the discoloration caused by precipitation of Sb nanoparticles. Although both Sb 3+ and Sn 2+ belong to the ns 2 -type emission center, the Sb 3+ -doped 60 ZnO –40 P 2 O 5 glass showed an emission with a weaker intensity and a broader band than Sn 2+ -doped 60 ZnO –40 P 2 O 5 glass. The emission decay of 1.0 SbO 3/2 –60 ZnO –40 P 2 O 5 glass was about 2.5 μs, which was shorter than that of 1.0 SnO –60 ZnO –40 P 2 O 5 glass. The obtained results suggest that the emission properties of ns 2 -type emission centers depend on several factors, such as element of emission center, chemical composition, and preparation scheme, which are easily and widely tuned in random amorphous materials.
