| Abstract: | The research status of the white LED phosphor was introduced as well as some special properties that high quality phosphor should have,such as emission centralized peak in some appropriate wavelength range,high quantum efficiency,good thermal and chemical stability,high absorbed rate of the excitation light,uniformity powder particles,low attenuation and high quenches temperature,and so on.And some methods to synthesize phosphor were also introduced;advantages and disadvantages of these methods were compared. |
