Abstract
Transparent oxyfluoride glassceramics containing PbF2Yb3+ Eu3+ RE3+ RE = Tm Ho Er nanocrystals were synthesized by secondary thermal treatment of lowmelting SiO2–PbO–PbF2–CdF2 glasses The optical absorption and luminescence of the rare earth ions were investigated Multicolor orange yellow green and blue upconversion luminescence was detected with excitation at 960 nm by an InGaAs laser diode The luminescence color characteristics could be controlled by varying the heat treatment regime
