PURPOSE:To provide the titled single crystal containing a slight amount of silicon, having low fluctuation of light emission and excellent light emission efficiency and useful as a scintillator for detecting radiation such as X-ray, gamma-ray, etc. CONSTITUTION:Each of CdO powder and WO3 powder having purity of 99.999% is added with 10<-6>-10<-3>mol of Si or SiO2 (in terms of Si). Equimolar amounts of the mixed CdO powder and WO3 powder are put into a platinum crucible and melted by heating with a high-frequency heater. A CdWO4 single crystal containing slight amount of silicon is grown from the molten mixture by Czochralski process.
