TNSC, RIKEN showcase deep ultraviolet LED technology


Industrial gas major Taiyo Nippon Sanso Corporation (TNSC) and Japan-based scientific research institute RIKEN have tested new LED technology to be used across a wide range of fields including sterilisation, disinfection, and medicinal applications.

The companies – which have conducted joint research in the sector – demonstrated AlGaN (aluminium gallium nitride) deep ultraviolet LED electroluminescence (EL) at a short wavelength of 226 nm (nanometre) using TNSC’s MOCVD (metalorganic vapour-phase epitaxy) technology. 

Having previously conducted tests with a 280 nm emission wavelength, the new test reported EL emission with a 226 nm with the TNSC SR4000HT in 2-inch x 3 wafers configuration.
