Controllable photoluminescence by melting-process temperature in SnO-containing glass

抄録

We prepared SnO–ZnO–B₂O₃ system glasses by means of melt-quenching technique with different melting-process temperatures in range of 1100–1500°C, and examined the impact of the process temperature on photoluminescent (PL) property. The glass obtained at 1100°C showed clear PL band at ∼2.8 eV at room temperature. As elevating the process temperature, a shoulder appeared at lower-energy side of the PL band, and eventually broad band with peak at ∼2.2 eV developed, resulting the clear orange PL. We demonstrated that the PL-color is controllable from blue to orange via white by change in the process temperature.
