Growth of trivalent ions doped PbWO₄ crystals and their scintillation properties

Abstract

Undoped and series of trivalent ions(including La, Y, Gd and Tb) doped PWO crystals were grown from 5N raw materials by using Czochralski technique. Trivalent ions doping improved the transmittance, fast components of luminescence and radiation damage resistance for compensating structure defects. Corresponding, the fraction of light yield at shorter collecting time was increased.

Compositionally Disordered Ceramic (Gd,Y,Tb,Ce)3Al2Ga3O12 Phosphor for an Effective Conversion of Isotopes’ Ionizing Radiation to Light

“…For the new promising applications, the radiation resistance of the material, combined with the thermal stability of the scintillation yield, are critical parameters. Crystalline materials activated with both cerium [40] and terbium [41][42][43] are tolerant to exposure to the electromagnetic component of ionizing radiation and high-energy protons. Codoping with Ce 3+ and Tb 3+ ions increases the radiation resistance of materials [44].…”

Photodielectric effect in lead molybdate monocrystals

“…Lead molybdate (PbMoO 4 ) and lead tungstate (PbWO 4 ) crystals have wide technical applications as materials for acoustooptic devices [1] and scintillators [2]. A special luminescent bolometer has recently been proposed [3] and it appears that PbMoO 4 and other luminescent crystals may find several new applications [4].…”
