摘要: The photoluminescence properties and energy transfer of a new Ce3+/Pr3+/Eu3+ co-doped solid-solution composition of Sr2.975-xLaxAlO4+xF1-x (LSAF) phosphor are investigated. Upon doping Pr3+ into lattices of LSAF:Ce host, a shoulder emission peak is observed at about 620 nm, owing to the transition of 1D23H4. Addition of Eu3+ to LSAF:Ce3+, Pr3+ phosphor results in a sharp emission peaked at 675 nm for the 5D07F3 transition and an increase of the intensity of red emission for Pr3+ with increasing Eu3+ concentration. The pathways of energy transfer among Ce3+, Pr3+, and Eu3+ are proposed to be responsible for color addition of a red component to the primary yellow emission, enabling a potential adjustable color for blue excitable warm white.
