Title: Strontium silicate-based phosphor and method thereof
Applicant: Korea Research Institute of Chemical Technology, Korea
'International application number: WO 2004/067677
Scientists in Korea are trying to patent a way to fabricate a strontium silicate-based phosphor with a europium activator. The authors say that the yellow-emitting phosphor can be used in combination with a blue LED to produce white light. They add that the phosphor shows a wide emission spectrum and that the main peak can be altered by changing the concentration of europium. "When the yellow phosphor is applied in the long wavelength ultraviolet LED and an active luminous LCD, the color purity can be improved and the luminous efficiency can be enhanced," say the authors.'
