Research Progress in the Preparation of Phosphor for White Light Emitting Diode

As a solid-state lighting source, white light emitting diode (LED) has become the most promising green lighting energy source in the 21st century with its three advantages of energy-saving, environmentalfriendly and green-oriented. The study summarized the research progress in the preparation of phosphor for white light emitting diode, analyzed and compared the effects of different materials and synthesis methods on its luminescence performance. The future development trend was also prospected.
