Abstract
luminescence is studied in , and the emission spectrum shows an intense and broad green emission band with two peak maxima (475 and 505 nm). The two emission bands are due to present in the two crystallographic distinct Sr sites in the host lattice. luminescence is studied in and shows a broad and bright blue emission band at around 430 nm under 350 nm excitation. The effect of co-doping is studied in phosphor. Thus, the co-doping of also enhances the absorption of in the near-UV region, where the light-emitting diode emission occurs. co-doped samples show broad-band emission ranging from 360 to 620 nm (blue to green–yellow), which results in white emission. This indicates partial energy transfer from to . Selected compositions of this phosphor material can find potential application in solid-state lighting.
