PHOTOSTABILISED ORGANIC MATERIAL

摘要

The photostability of organic material is enhanced by the incorporation of a plurality of particles which may for example have a diameter of 0.03 microns to 2.5 microns. The organic material may be a light absorbing material and may be photoluminescent or electroluminescent. Compositions in accordance with the invention incorporating an electroluminescent material of enhanced photostability may be used in an Organic Light Emitting Diode (OLED).
