Abstract

Optical-quality ZnWO4:Eu3+ single crystals are grown by the low-gradient Čzochralski method. In a temperature range of 77-400 K, the ZnWO4:Eu3+ single crystals exhibit intense red photoluminescence with CIE chromaticity coordinates (x = 0.614, y = 0.366) and a correlated color temperature of 1754 K. It is suggested that Eu3+-activated ZnWO4 is a promising luminophore for the use in the phosphor-converted light-emitting diode technology.
