Abstract: The present major methods for preparing of white light emitting diodes (LED), such as RGB 3-element color, blue LED exciting YAG: Ce3+ phosphors and emission of Dy3+ ions, were reviewed. The preparing process and structure system of the phosphors required in various methods as well as their advantages and disadvantages were introduced primarily. Some problems and development trends in the field of white light emitting diodes were discussed simply.

Keywords: white light emitting diode; phosphor; RGB 3-element color
