The authors report on the UV-excited photoluminescence measured in Sb 2O 3-ZnO-P 2O 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 60ZnO-40P 2O 5 glass showed an emission with a weaker intensity and a broader band than Sn 2+-doped 60ZnO-40P 2O 5 glass. The emission decay of 1.0SbO 3/2-60ZnO-40P 2O 5 glass was about 2.5 μs, which was shorter than that of 1.0SnO-60ZnO-40P 2O 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.
