The emission hue can be tuned from cool white to white, and finally to warm white light due to the energy transfer from Bi3+ ions to Sm3+ ions. Simultaneously, two kinds of sites for cations (Ca2+) in the host were considered.

Luminescence Efficiency

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.
