Abstract
The present invention is directed to photonic devices which emit or absorb light with a wavelength shorter than that GaN photonic devices can emit or absorb. The devices according to the present invention are formed using molybdenum oxide of a high purity as a light emitting region or a light absorbing region. New inexpensive photonic devices which emit light with a wavelength from blue to deep ultraviolet rays are realized. The devices according to the present invention can be formed at a temperature relating low such as 700° C.
