• Remote phosphor
• Graphene
• High power LEDs

A hybrid remote phosphor with single-layer graphene was developed for the fabrication of warm white LEDs, and with an off-the-shelf blue LED operating at 350 mA it produced a high luminous flux of similar to 64 lm at 100 degrees C. The remote use of a single layer of graphene with a phosphor has a multi-functional role that improves the luminous properties, long-term stability and thermal properties of LEDs. We suggest that it can be expected to play an important role as a promising candidate for next-generation remote phosphors of high-power LEDs.
