Abstract

This work investigates the porosity of ErF3 doped CaF2 crystals using the Rutherford back-scattering (RBS) method. Two ErF3:CaF2 samples of 2.0 and 5.5% doping ratios were prepared using the Bridgman method. The RBS spectra of these samples at two incident angle configurations of the projectile alpha, i.e., 0 and 30 degree, were collected using the Rutherford back-scattering spectrometer at the Joint Institute for Nuclear Research in Dubna, Russia. The measured spectra were analyzed with sample models of porous materials using the SIMNRA program. It turns out that the porous volume ratio and diameter are probably in the intervals of 18 to 22% and 2.4×1018 to 3.0×1018 atoms per cm2, respectively. However, the RBS method exhibits significant uncertainty, impeding our ability to establish a correlation between porosity characteristics and doping ratios.
