Abstract:In this work, we prepared three CaWO4 single crystals (CaW‐0, CaW‐ and CaW‐3) doped with rare earth elements (REEs) at nominal mass fractions of 50, 250 and 5000 μg g‐1 using the Czochralski method. Electron probe microanalysis (EPMA) and laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) were employed to evaluate the within‐ and between‐unit homogeneity of major elements and REEs, respectively. The within‐unit variation (sr) of 0.40–0.84% and between‐unit sr of 0.14–1.48% for major elemen… Show more
