Abstract
Rapid and continuous production of phosphor (YAG∶Tb) fine particles by hydrothermal synthesis in supercritical water was studied. At temperatures higher than the critical temperature of water, continuous and rapid (3 ) 3 , Y(NO 3 ) 3 , and TbCl 3 ] as aqueous solutions with an alkali molar ratio {[OH – ]/([NO 3 – ] + [Cl – ])} of 1 and a rapid heating method. No additional thermal treatment was necessary to obtain crystalline products.Keywords
