Abstract
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).
Claims38
An Organic Light Emitting Diode which comprises a composition incorporating an electroluminescent organic material sandwiched between two electrodes wherein said composition contains a plurality of particles with a size of 1 to 20 nanometers which serve to enhance the photostability of the organic material.
An Organic Light Emitting Diode which comprises a composition incorporating an electroluminescent organic material sandwiched between two electrodes wherein said composition contains a plurality of particles for enhancing photostability of said organic material wherein the particles have a diameter which is not less than 1000 times smaller and not more than 6 times greater than the wavelength of light in which the organic material is desired to be photostable.
A laser comprising a composition incorporating a photoluminescent material containing a plurality of particles which serve to enhance photostability of the organic material.
A composition comprising an organic material and a plurality of particles which serve to enhance photostability of the material.
