With the recent advent of efficient blue LEDs the opportunity to produce white emitting LEDs is now present. As a result, Phosphors for LEDs have entered exciting times.
White LEDs are made by coating with a phosphor. A proportion of the blue light emitted is absorbed by the diode therefore emitting light across the rest of the visible spectrum. Typically one or two phosphors are used to convert the blue to white. Either a single broad yellow phosphor or a combination of green and red will produce the desired effect.
Can we help with your Phosphors for LEDs requirements?
We have been developing phosphors for LEDs to match these requirements for several years now. As a result we have a number of materials suitable for various applications. Please contact us to discuss any requirements. Further more we can advise you on the appropriate materials to use.
