Self-Activated Green-Yellow Emitting Gd₂CaZnO Phosphor for Efficient Ultra-Violet Light-Emitting Diodes.

A new self-activated green-yellow emitting Gd₂CaZnO (GCZO) phosphor was synthesized using solid-state reaction method at high-temperature. XRD analysis confirmed the orthorhombic structure of the sample with the Pbnm space group. SEM micrographs reveal the irregular morphology with micron sized particles.
