Abstract

Basic optical properties and radiation responses of undoped, Tm ³⁺ 1.0% and 2.0% activated Ca₃(BO₃)₂ (CBO) crystalline scintillator prepared by the micro-pulling down (μ-PD) method are reported. Tm³⁺: CBO crystals showed three weak absorption bands around 190, 260 and 350 nm, owing to the Tm³⁺ 4f-4f transition. Strong blue luminescence peaks at 360 and 460 nm which are ascribed to the ¹D₂-³H₆ and ¹D ₂-³F₄ transitions of Tm³⁺ respectively were observed under ²⁴¹Am 5.5 MeV α-ray excitation. The scintillation light yield of 2.0% Tm³⁺-doped CBO crystal was evaluated to be about 250 ph/n from the ²⁵²Cf excited pulse height spectrum.
