摘要

The optical properties and radiation hardness of large-size PbWO₄:Y crystal grown with modified Bridgman method were investigated through characterization on the optical transmittance, X-ray excited luminescence, light yield and irradiation damage of series 24 × 24 × 24 mm³ block crystals cut from a long as-grown ingot. From the measuring results of the sequential small block samples it can be concluded that large-size modified Bridgman grown PbWO₄:Y crystals have excellent uniformity of optical properties and radiation hardness.
