Abstract :
This paper presents the development of new Ce-doped, fast and high effective-Z mixed Lux(RE3+)1−xAP:Ce crystals. These crystals have been grown by the Czochralski method and good results have been obtained with x=0.1, 0.2 and 0.3 for Y3+ ions and roughly between x=0.6 and 0.7 for Gd3+ ions. Relative light yields measured for the Lux(RE3+)1−xAP:Ce crystals are 40–75% higher than for BGO and are comparable to the light yield of YAP:Ce crystal. Measured energy resolutions at 662 keV range over 8–15.3% fwhm and are close to the energy resolution obtained with YAP:Ce. Thermally stimulated luminescence (TSL) measurements above room temperature have also been performed: in accordance with the expected effect of trap states on scintillation efficiency, an anticorrelation between TSL intensity and light yield is found.
