Abstract: A method for forming an oxide coated substrate comprising heating a pre-coating mixture in the presence of a substrate to synthesize an oxide coating on the substrate. The pre-coating mixture comprises a solubilized reducing additive, a solubilized oxidizing additive, and the substrate. The heating is conducted at a temperature sufficiently high enough to exothermically react the solubilized reducing additive and solubilized oxidizing additive and low enough to control the phase and composition of the oxide.

Abstract: Some embodiments disclosed herein include a lighting apparatus having a composite. The composite may include a first emissive layer and a second emissive layer.
