摘要：Organic light-emitting diode based on the principle of emissive electroluminescent layer is a thin film of organic compound which emits light in response to an electric current and are used to create digital displays and solid state lighting. The main objective of this thesis work is to synthesis and characterise nipa palm extract with spectrophotometer . A key issue associated with this research work is the determination of the peak absorbance for the seed and the husk solutions at 660nm and 580nm respectively . The phytochemical screening of the husk and seeds of Nipa fruiticans revealed the presence of polyphenols and tannins in the husk while the seeds showed traces of alkaloids. Thus, the nipa palm seed and husk material have potential applications of red and yellow colours OLED which guarantee good color stabilization.
