Polymerizable complex combinatorial chemistry method for searching on the composition of oxide-phosphors using Combi-chem synthesizing apparatus

摘要

PURPOSE: Provided is a combinatorial chemical synthesis of complex polymerization for detection of composition rate of oxides-based fluorescent material using a combinatorial synthesis device. The detection is made by several small reactors of combinatorial chemical synthesis which synthesize the fluorescent material powder of the uniform compositions rapidly and easily according to the control of a computer. CONSTITUTION: The above synthetic method comprises: filling the solution mixtures of 0.1-1.0 mole concentration of metal ion solution, a complex forming agent selected from citric acid and ethylenediaminetetracetic acid(EDTA) and ethylene glycol, into several solvent storing device, to make the 0.01-0.2g of final fluorescent material where the mixture solution of complex forming agent and ethylene glycol is in a mole ratio of 1.5-5 : 10-30 and the mixture is used in 2-5 equivalent weight of the above metal ion, based on the complex forming agent; introducing into test tube reactors placed front, back, left and right in a certain distance by the solution inputting device controlled by a computer according to the component ratio changing the input weight by the location controller controlled by the computer; moving the above reactors to the forced air circulation dryer, drying and heating the complex material containing metal solution, excess complex-forming agent and ethylene glycol to polymerize and synthesize the complex polymer precursor; and making the fluorescent material of the different composition by heat treating the above test tubes in the electric oven to eliminate the organic materials, cooling and moving the heat treated powder precursors to the aluminum plate with several cells and heat treating again controlling the atmosphere.
