Blue-emitting Sr1-xCaxLu2O4:Ce3+phosphors for high CRI white LEDs*

Yipeng Zhou et al.

Summary: A broadband blue-emitting Sr1-xCaxLu2O4:Ce3+ phosphor was synthesized for near-UV pumped white light-emitting diodes (w-LEDs). By partially substituting Sr2+ with Ca2+ (x = 0-0.2), the emission peak red-shifted, external quantum efficiency increased, and thermal stability improved in Sr1-xCaxLu2O4:Ce3+. The potential of Sr1-xCaxLu2O4:Ce3+ as blue phosphors for high CRI w-LEDs application was demonstrated.

Photoluminescence properties of Tb3Al5O12:Ce3+, Mn2+ phosphor ceramics for high color rendering index warm white LEDs

Yutong Duan et al.

Summary: The Tb3Al5O12:Ce3+, Mn2+ phosphor ceramics were fabricated with different doping concentrations of Mn2+-Si4+ ions pair, allowing for emission colors to be changed from yellow-green to orange-red. Red emission was mainly attributed to transitions of Mn2+ ions via energy transfer under 460 nm excitation. By optimizing the phosphor ceramic with 460 nm blue LED chip, a white light with low CCT of 3426 K and high CRI of 84.4 was achieved, showcasing the potential for warm white LED applications.
