In 2009, Denka launched ALONBRIGHT nitride phosphors for the LED industry, and has worked to expand the catalog to include a range of finely tuned Green, Orange, and Red products, each bringing added-value to customers across the globe. DENKA’s Green β-type SiAlON and Orange α -type SiAlON nitride phosphors are engineered for reliability and stable brightness, even under the stress of higher temperature applications. CASN and S-CASN Red phosphors are also featured in the lineup, and contribute significantly to enhanced color rendering at higher brightness in the LED product. As of 2014, Denka also launched a new red phosphor, KSF, to contribute to achieving a wider color gamut in LED TV and Smartphone/Tablet applications. Whether found in LCD backlighting or in general illumination, Denka ALONBRIGHT phosphors also work hand-in-hand when blended to achieve stunning color in any application.



SiAlON, CASN/SCASN, and KSF phosphors: ALONBRIGHT exceed conventional silicate phosphors in reliability for heat-resistance beyond 100oC and humidity-resistance, while achieving superior brightness in LED packages.
