One of the ways to optimize energy consumption and reduce pollutants in the environment is to reduce energy consumption for brightness. In this field LED bulbs have attracted a great attention due to many advantages they have over other types of lamps, in addition to high efficiency. The construct of these types of lamps, consists of a blue color diode and a phosphor that is applied to it. Phosphor must be in yellow spectra or a combination of red and green in order to obtain a white color. Since being the light produced close to sunlight is important, several parameters are considered in the selection of materials. In phosphor synthesis for white LED, the purpose of doping is increasing Color Rendering Index. The purpose of this paper is to study a variety of materials that can be applied as phosphorus on a diode to create white light.
