SC799: Solid State Lighting Phosphors
The development of blue and UV InGaN light emitting diodes is being complemented by a parallel exploration of new phosphor material systems for use with these new diode technologies. Currently, two approaches are being investigated: the use of a blue LED phosphor pump which combines with the phosphor emission to give a white spectrum, and secondly the use of a tri-color red, green and blue phosphor set, which are pumped in the near-UV, between 380-406 nm. For both approaches it is necessary to develop highly efficient and long-lived phosphor materials that are well matched to the excitation conditions of the diode, and whose spectral emission properties produce a high color rendition index (>95). This course, therefore, complements the Solid State Lighting I & II courses (SC490 & SC770), by providing an in depth review of the recent developments in phosphors for SSL. Examples of excitation and emission spectra will be given for the important material systems. The scope is to provide a state-of-the-art review of Solid State Lighting Phosphors from both the perspective of the solid state device engineer and the lighting designer.
