Critical review on lanthanide activated LED phosphors

Broad range of phosphors has been utilized for LEDs in past few years, subsequently, encourages the phosphor-converted LEDs (pc-LEDs). Proposed article gives an idea about the different color tunable phosphors used in solid state lighting. Different properties of different color emitting phosphors have been done with the mixing of rare earths in the host lattice of luminescent centered materials which shows color emission in the visible range. There is a concise approach toward the different characteristics and records related with the color quality and execution of pc-LEDs. So this article mainly deals with role lanthanides in LED phosphors and their characteristics in the field of luminescence. (paper)
