LED phosphor processing

Homogeneous LED phosphor materials

Freeze Granulation offers a unique technology for to make homogeneous LED phosphor materials resulting in improved photoluminescence properties and thus, Freeze Granulation will give you high power LEDs with superior final properties. Most LEDs that are emitting a soft white light have been covered by a yellowish phosphor coating or plate usually made of cerium doped yttrium aluminium garnet (YAG:Ce) crystals, which have been processed using powder processing techniques and bound into a ceramic plate, glass or with a resin.
