Highly effective synthesis and photoluminescence of Sr_2Si_5N_8+Eu~(2+) red-emitting phosphor for LEDs

摘要

We developed a highly effective and self-sustaining route for synthesizing Sr_2Si_5N_8:Eu~(2+) red-emitting phosphor particles for use in light emitting diodes (LEDs). The phosphors thus synthesized showed excellent emission characteristics under a blue excitation wavelength of 450 nm, had a uniform particle size distribution, and showed high performance in LED packages.
