A series of five samples of Borophosphate glasses doped with SrO and Li 2 O within the composition of 20(B 2 O 3 ) + 30(P 2 O 5 ) + x (SrO) + (50-x) (Li 2 O) where x = 10, 20, 30, 40 & 50. The Glass Samples were prepared by the melt quenching technique, and the samples were annealed to remove if any thermal strains present. Glasses were characterized by DSC studies in the temperature ranges from 423-673K to determine the glass transition temperature (Tg). Here Tg increases linearly with SrO mole fractions, the FTIR study shows the existence of different structural and functional group of B 2 O 3 , P 2 O 5 such as BPO 4 , BO 3 and BO 4 units in the network. Borophosphate glasses containing SrO and Li 2 O, which exhibits different IR bands, related to SrO structural units.
