Real structure and diffuse scattering of Sr0.5Ba0.5Si2O2N2:Eu2+ ― A highly efficient yellow phosphor for pc-LEDs

Sr0.5Ba0.5Si2O2N2:Eu2+ is a promising new phosphor for white light phosphor converted (pc)-LEDs. The material shows broad-band emission due to parity allowed 4f6(7F)5d a' 4f7(8S7/2) transition in the yellow spectral range ( lambda
