Lithium borate (LBO) single crystals doped with Cu and Ag (0.25mol% each) (Li₂B₄O₇:Cu,Ag) are grown by The  Czochralski method. The thermo luminescence read out on Li₂B₄O₇:Cu, Ag crystals showed three glow peaks  at ˜375, 441 and 516K for the heating rate of 1K/s. The thermo luminescence sensitivity of the grown Li₂B₄O₇:Cu, Ag single crystals is found to be 5 times TLD-100 and a linear dose response in the range 1 mGy to 1kGy. The glow curve deconvolution reveals nearly first order kinetics for all the three peaks with  trap  depths 0.77, 1.25 and 1.34eV respectively and corresponding frequency factors 1.6 x 10⁹, 1.3 x 10¹³ and 6.8 x 10¹¹ s ^-1. The continuous wave optically stimulated luminescence (CW-OSL) measurements were performed on the LBO:Cu, Ag single crystals using blue light stimulation. The traps responsible for the three thermo luminescence peaks in Li₂B₄O₇:Cu, Ag are found to be OSL sensitive. The qualitative correlation between TL peaks and CW-OSL response is established. The photoluminescence studies show that in case of co-doping of Ag in LBO: Cu the emission at 370n min Cu states dominates over the transition sin Ag states implying doping of Ag plays a role as sensitizer when co-doped with Cu and increases over all emission.
