A scintillator material comprises a rare-earth halide coated with a layer comprising a resin and a pigment. In an embodiment, the scintillator material is used in an ionizing-radiation detector, and in particular embodiment, a gamma camera. The layer can adhere well and act as an absorbent or reflector depending on the color of the pigment.
