Abstract

(Eu_0.01, Gd_0.90, La_0.09)₂Si₂O₇ (Eu:La-GPS) and (Tb_0.01, Gd_0.9₀, La_0.09)₂Si₂O₇ (Tb:La-GPS) crystals were grown by the floating zone method, and their optical and scintillation properties were investigated. Gd³⁺-to-Tb³⁺ or -Eu³⁺ energy transfer processes were found, and photo-luminescence and radio-luminescence emission spectra showed ⁵D₀-⁷F_i (i = 1-4) Eu³⁺ transitions in Eu:La-GPS, and ⁵D₃-⁷F_i (i = 3-6) and ⁵D₄-⁷F_i (i = 3-6) transitions in Tb:La-GPS. Using these scintillators, alpha-ray imaging was possible with a CMOS camera. These materials can be used for X-ray detection as well.
