Abstract

Ce and Pr doped YCOB single crystals were grown by the micro-pulling down ( $\mu - \text{PD}$ ) method and characterized as for the structure and chemical composition. The expected 420 nm emission of $\text{Ce}^{3 + }$ 4f-5d has been observed in Ce:YCOB. Pr:YCOB shows broad emission spectrum peaking around 350 nm and this emission can be well ascribed to the 5d–4f emission of $\text{Pr}^{3 + }$ . Luminescence and scintillation characteristics of these crystals were also investigated.
