Abstract
The properties of thermoluminescence (TL) observed from various mixed rare earth (RE) phosphate powders La1-x-yCexTbyPO4 are reported. TL peaks appear around -175 degreesC, -135 degreesC, -80 degreesC, -35 degreesC and +25 de greesC and the TL emission spectra of La1-x-yCexTbyPO4 are mainly composed of characteristic line transitions of Tb3+ ions, The results show that the co-doping with Ce3+ is not required to observe the TL emission of Tb3-. A m odel for the recombination mechanisms of the various TL peaks is discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
