Abstract: Cu<sup>+</sup> activated Li<sub>2</sub>BPO<sub>5</sub> phosphor is synthesized by one step wet chemical technique and exposed to gamma-rays of <sup>60</sup>Co source for their thermoluminescence (TL) properties. The XRD technique shows the crystalline nature of the prepared material. Photoluminescence (PL) emission spectra of Li<sub>2</sub>BPO<sub>5</sub>:Cu phosphor show the strong prominent peak at 368 nm in the violet region of the visible spectrum assigned to the transition of 3d<sup>9</sup>4s<sup>1 </sup>↔ 3d<sup>10 </sup>of Cu<sup>+</sup><sub> </sub>ion. Thermoluminescence characterization of prepared Li<sub>2</sub>BPO<sub>5</sub>:Cu is low Z (Z<sub>eff </sub>= 10.29) phosphor shows the prominent TL glow peak at 143<span style="font-family:Symbol;mso-ascii-font-family:" times="" new="" roman";="" mso-hansi-font-family:"times="" roman";mso-char-type:symbol;mso-symbol-font-family:="" symbol"="" lang="EN-GB">°C at higher temperature and intensity is 2.6 times less than that of standard TLD CaSO<sub>4</sub>:Dy (Z<sub>eff </sub>= 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. </span>
