Abstract
Transparent oxyfluoride glass-ceramics containing PbF2:(Yb3+, Eu3+, RE3+) (RE = Tm, Ho, Er) nanocrystals were synthesized by secondary thermal treatment of low-melting SiO2–PbO–PbF2–CdF2 glasses. The optical absorption and luminescence of the rare earth ions were investigated. Multi-color (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.
