Abstract

Phosphor packages for a laser-heat thermoluminescence radiation-dosimetry system have been analyzed with Rutherford Backscattering Spectrometry and X-ray Photoelectron Spectroscopy. Samples consist of 20–50 μm diameter powder grains of CaSO4: Tm and LiF: (Mg, Ti) phosphor embedded in a transparent silicone matrix about 60 μm thick. Our principal finding with regard to layer morphology indicates an inhomogeneous outer layer of areal density at least ∼300 μg/cm2 depleted of phosphor and contaminated with boron.
