| Abstract: | White LED is an environmental protection and energy-saving green color lighting,which including a series of advantages such as a low voltage,low power consumption,high reliability and long life.Nowadays it is a trend to product high color rending index,low color temperature and high power white LED for its development.However the performance of the red emitting phosphor will affect the color rending index and the color temperature of the white LED extremely.This paper reviewed latest research results and the nowadays development about luminescent properties of materials for red-emitting phosphor used in white LED,putting emphasis on those of sulphide,nitride,tungsten and molybdenum.And the promising development in such reaerach areas was suggested. |
