LED phosphor powder/ luminescent powder for LED Lamps, blue light Lamps White LEDs are made by coating them with a phosphor that absorbs a proportion of the blue light emitted by the diode and 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 like YAG or a combination of green and red will produce the desired effect. We have been developing phosphors to match these requirements for several years now and have a number of materials suitable for this application. Please contact us to discuss any requirements you may have in this regard and we can advise you on the appropriate materials to use.
