Ultraviolet-assisted synthesis of organic/inorganic hybrid nanocomposites and their application for lifetime enhancement of light emitting diodes

Ultraviolet (UV) curable organic/inorganic hybrid nanocomposites with excellent gas barrier effect, good adhesion strength, high refractive indices, moderate hardness, and fast curing speed have been successfully quickly synthesized by UV irradiation and utilized for the encapsulation of light emitting diodes (LEDs). In addition, the experimental results reveal that lab-made nanocomposites effectively resist the penetration of oxygen and moisture in the air into the LEDs and thus enhance their lifetimes to achieve 18,300 h while those without encapsulation are only 2400 h.
