Abstract:

Novel Na3YSi2O7: Sm3+, Eu3+ phosphors for white light-emitting diodes were prepared by high-temperature solid-state reaction. The photoluminescence excitation and emission spectra, energy transfer from Eu2+ to Tb3+ are investigated in detail. The current research suggests that Na3YSi2O7: Sm3+, Eu3+ phosphor is a potential candidate for application in Phosphor-converted LEDs.
