Abstract: PURPOSE: A method of manufacturing nano crystalline silicon is provided to manufacture a hydrophilic or hydrophobic silicon particle based on a capping reagent. CONSTITUTION: A method of manufacturing nano crystalline silicon comprises the following steps. A capping reagent chosen from a reduced agent, C5-C20 alcohol, amin, thiol or fatty acid is added to an organic solution. Tetraehoxysilane(TEOS) or tetramethoxysilane(TMOS) are added to the organic solution to manufacture a spraying solution. The manufactured silicon spraying solution is added to a phase separating solution. The mixed solution from the phase separating solution is separated to make a silicon solution.
