LED Phosphor for LED lamp, LED packages and etc.
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.
