摘要：
Pure lead germanate (LG), 0.1 wt% Nd+3 doped (LG.1 Nd+3) and 0.2 wt% Nd+3 doped (LG.2 Nd+3) lead germanate single crystals were grown by controlled cooling of melt. Room temperature pyroelectric coefficient p(T) was found to increase with doping. In LG.1 Nd+3 doping enhances p(T) and figure of merit and there by increases the applicability of lead germanate as a pyroelectric detector.
