Investigation of the luminescent properties and energy transfer mechanisms in Gd3TaO7: Bi3+, Eu3+ phosphors for their potential application in full-spectrum WLED.

In Gd3TaO7:0.01Bi 3+ , y Eu 3+ , the tuning of light from blue and green to red under UV excitation was achieved by adjusting the concentration of Eu 3+ , and a single-phase white phosphor suitable for a 365 nm LED chip was successfully synthesized.
