This research studied the recycling of borosilicate glass wastes from damaged laboratory glassware. The luminescent glasses were prepared by doping waste powder with rare earth ions, namely, dysprosium ions (Dy3+) and samarium (Sm3+), as well co-doping Dy3+ Sm3+ at a concentration 2% weight. sintering process was conducted in microwave oven for duration 15 min. photoluminescence spectra doped obtained under excitation 401 nm 388 nm. results showed that emission characteristics depended on concentrations wavelengths. Upon nm, co-doped exhibited maximum peak 601 (yellowish orange region CIE chromaticity diagram) due to energy transition 4G5/2 6H7/2. When excited however, similar characteristic peaks (white diagram), but position exhibits red shift. could be attributed an increase amount non-bridging oxygens (NBOs) co-doping.
