520-523Cu+ activated Li2BPO5 phosphor is synthesized by one step wet chemical technique and exposed to gamma-rays of 60Co source for their thermoluminescence (TL) properties. The XRD technique shows the crystalline nature of the prepared material. Photoluminescence (PL) emission spectra of Li2BPO5:Cu phosphor show the strong prominent peak at 368 nm in the violet region of the visible spectrum assigned to the transition of 3d94s1 ↔ 3d10 of Cu+ ion. Thermoluminescence characterization of prepared Li2BPO5:Cu is low Z (Zeff = 10.29) phosphor shows the prominent TL glow peak at 143°C at higher temperature and intensity is 2.6 times less than that of standard TLD CaSO4:Dy (Zeff = 15.3) phosphor, but almost 7.8 times more than that of well known LiF: Mg, Ti low Z phosphor. It may be one of the candidates for thermoluminescence dosimetry (TLD) of ionization radiations.
