An organic light emitting diode (OLED) is a solid state device like the LED but composed of several layers in which the emissive electroluminescent layer is a film of organic compounds which emit light in response to an electric current.

multi-functional acrylate cross-linker, free radical initiator.
When UV-vis light exposed, low viscosity UV-curable materials self-polymerize forming polymer network. (It will be rigid layer.)
of carrier is higher at interface than surrounding. So, the carrier diffuses.
The built-in potential by different work functions of the electrodes affects.
1. sp2-hybridization of the valence electrons of two carbon atoms lead to molecular π- and σ-bondings.
2. Electrons in π bond are less influenced by nuclear relatively.

polymers or biomaterial, in order to confine the growth. Occasionally, the selective or preferential adsorption of capping agents onto particular crystallograp- hic facets during the growth stage permits diverse shapes to be produced, for example triangles, hexagons, disks, rods and multipods. Here, the capping agent functions by inhibiting the growth of a particular crystallographic direction. A
