The search for the Holy Grail of the LED industry has taken another step forward. GELcore, Valley View, Ohio, and GE Global Research, Niskayuna, N.Y., recently announced they have developed a phosphor that can be combined with visible LED chips to produce white light LEDs. The patent-pending phosphor will serve as an alternative to YAG-based materials.
According to a GELcore press release, the phosphor can be combined with LED chips with emission between 430 nm and 490 nm to create the white light. The company plans on using the technology for end use applications like backlights for LCDs in cell phones and PDAs and automotive interior lighting.
The company plans to make the technology available for functional use later this year.
