摘要: Abstract The polycrystalline compounds of Li6Y(BO3)3: Ce3+ and Sm3+ co-doped samples were prepared by using standard solid state reaction method. energy levels the doped lanthanide ions (Ce3+ Sm3+) in borate host materials investigated Thermoluminescence (TL) glow peak analysis. samples, exhibits TL at higher temperature region around 511 K whereas individually sample has 433 K. X-ray excited emission spectra carried out for all found characteristic bands. trap depths (E) calculated several methods, namely shape method or chen's (PS), variable heating rate (VHR), initial rise (IR) computerized curve deconvolution (CGCD). mean activation to be 1.21 (0.07±) eV frequency factor 1.38 × 1011 Sec−1. predicted level values compared good agreement. This primarily results suggest that scheme can help development new suitable dosimetry.
