Optoelectronic material and device application, and method for manufacturing optoelectronic material

摘要

An optoelectronic material, device applications, and methods for manufacturing the optoelectronic material are provided to make it possible to obtain stable characteristics without deterioration of luminescence over time in the atmosphere. The optoelectronic material is composed of a porous silicon the surface of which is nitrided to form a silicon nitride layer thereon. This allows a stable electroluminescence to be obtained, without oxidation of the surface of the porous silicon.
