Synthesis and optical characterization of pure and nickel doped gallium nitride nanocrystals

In the present Letter, Ga1−xNixN (0 ≤ x ≤ 0.1) nanocrystals have been synthesized by facile solvothermal method. Crystallographic characterization of synthesized materials has been done, using powder X-ray diffraction technique, reveal the formation of wurtzite (hexagonal) structured GaN nanocrystals. Electron microscopic studies have been carried for the detailed topographical and morphological analysis of synthesized nanomaterials....
