Eu/Tb codoped aluminoborosilicate glasses were fabricated by high temperature melting-quenched
technique and their luminescence properties were investigated by excitation and emission spectra. Under
376 nm excitation, blue, green and red emission bands were simultaneously observed at 425 nm, 485 nm,
540 nm and 611 nm, respectively. The broad blue emission band centered at 425 nm was originated from the
reduced Eu2+ ions, which were reduced from Eu3+ ions at high temperature in an ambient atmosphere and
the reduction process may be related with the optical basicity of glass matrix. A complex bright white
light emission was obtained for 0.5 mol Eu2O3, 0.5 mol Tb2O3 codoped aluminoborosilicate glass with
CIE-X=0.31 and CIE-Y=0.33. The energy transfer among Eu3+, Eu2+ and Tb3+ ions was also discussed.-Eu/Tb codoped aluminoborosilicate glasses were fabricated by high temperature melting-quenched
