An esteemed Rutgers University Professor of Chemistry has developed bright white light emitting, and tunable wavelength, organic-inorganic hybrid materials based on II-VI and I-VII elements. The novel materials can be used as a phosphor coating to replace costly Rare Earth Oxides for white light LEDs and fluorescent lamps, materials for displays, and further research could develop the material into direct electroluminescent devices.
This bulk material has a simple 1-step, 1-pot solution process for making the organic-inorganic crystal. The material has a well controlled and tunable optical emission; a very broad emission is observed with a bandwidth spanning the entire visible region from 400-700 nm, resulting in an overall white light source with excellent CIE coordinates, CRI and CCT, when excited by an UV excitation source. In addition, the material has the ability to be tuned to a narrow visible emission.
