Modification of Organic Phosphor Using Inorganic-organic Hybrid Polymer as Conversion Materials for Solid State Lighting: From Its Synthesis to Application

Research and development of solid state lighting (SSL) is very important path to achive a large energy saving since lighting consume a significant amount of energy. Most of commercial SSL configurations are a combination of inorganic LED with inorganic phosphor as color conversion material. Besides well known inorganic phosphor. organic phosphor also have potential application as color conversion material for SSL Organic phosphor are well know having high quantum efficiency and low production cost, however they have limitation on their stability. In order to improve organic phosphor stability and used them for color conversion material for SSL, we develop hybrid inorganic-organic polymer based on monomer of (3-(Trimethoxysilyl) propyl methacrylate) and (3-Glycidyloxypropyl) tri methoxysilane), which have higher stability and employed it as an host matrix for organic phosphors. In order to obtain a white envision we used Nile Red, Coumarin 6, Coumarin 1, and DCM (4-(Dicyano methylene)-2-methy1-6-(4- dimethylaminostyry1)-4H-pyran) as RGB (Red Green Blue) organic phosphor and optimized their compositions. Some of thin film fabrication techniques such as spincoating, screen printing and spraying were employed to obtain chin film of organic phosphor. We present some results on development of organic phosphor using the hybrid polymer host matrix and some examples of their application as color conversion material in SSL configuration using direct path excitation and light wave coupling approach.
