Towards blue excitable line emitters (Conference Presentation)

Paper Abstract

Narrow band (i.e. line) emitters have an enormous potential for use in LEDs, as they will allow both improvement of color rendering while maintaining high lm/W, and open up new spectral engineering possibilities for specific applications. The major bottle neck for implementation of line emitters in LEDs, is the lack of absorption in the blue spectral region of conventional trivalent lanthanide doped phosphors. In this talk, I will present a new nanoscale approach to engineer phosphor materials, which allows tuning of absorption and emission wavelengths over a wide range of the spectrum. The underlaying mechanism of these engineered phosphors is interparticle energy transfer, which will be discussed in more detail.
