The SnO2 co-doped lithium potassium borate glasses doped with 0.05, 0.10, 0.25 and 0.50 mol of Cu were synthesized by the melt quenching technique. The SnO2 co-dope was added to the compounds in the amounts of 0.05, 0.10, and 0.20 mol. The photoluminescent spectrum for different concentrations of copper was studied. It was observed that the intensity of blue emission (450, 490 nm) varies with concentration mol. In addition, with different concentration of SnO2 to 0.10 mol Cu, the influence of the luminescence has been observed to enhance intensity and shifted to blue and red (490, 535 nm) emissions. © 2012 American Institute of Physics.
