The white light emission of BaY2Si3O10:0.01 Bi3+, mEu3+ phosphor can be realized and utilizing the energy transfer under near UV light pumped. The energy transfer efficiency between Bi(i) and Bi(ii) change with the temperature increasing due to phonon-assisted process. It is rare in the experiment on directly proof with the phonon-assisted energy transfer.

Sm3+, Ce3+ codoped Al2O3–La2O3–SiO2 glasses were prepared and their luminescence properties were characterized. Blue-cyan to orange-red tunable luminescence was observed from these glasses with different excitation wavelengths ranging from 385 to 410 nm. White light emission with internal luminescence efficiency 42% has been observed using commercially available purple light-emitting-diode excitation. The energy transfer between Ce3+ and Sm3+ has also been investigated from fluorescence decay curves and spectral properties.
