PURPOSE: A manufacturing method of zinc sulfide crystalline nanophosphor is provided to quickly manufacture uniform-sized phosphor particles of 200-500 nm without cohesion in low temperatures by using combustion sintering method. CONSTITUTION: A manufacturing method of zinc sulfide crystalline nanophosphor comprises: a step of manufacturing mixed solution containing zinc chloride and cupric chloride; a step of manufacturing sulfur compound solution; a step of manufacturing polymer dispersant solution; a step of manufacturing zinc sulfide precursor in which copper and chloride are added, by adding the mixed solution and the sulfur compound solution into the polymer dispersant solution by ultrasonic wave-spraying method with controlling pH of 2-4 by adding acid; and a step of cleaning the zinc sulfide precursor; a step of heat-treating the products; and a step of shattering the products.
