Much progress has been achieved in LEDs since the 1980s. They have become much more efficient and are now the point light sources of choice. Recent technological progresses in the color conversion by suitable phosphors has brought solid-state lighting nearer to reality.229... 

Tony Cheetham was a member of the Chemistry faculty at Oxford, 1974-1991, and has been at the University of California at Santa Barbara since 1991. He is Professor in both the Materials and Chemistry Departments at UCSB, and since 2004 has been the Director of the new International Center for Materials Research (ICMR). Cheetham s research interests lie in the area of functional inorganic materials and currently include hybrid framework materials, phosphors for solid state lighting, and inorganic nanoparticles. 

Apart from the applications mentioned earlier, it is worth mentioning the extended usage of YAG Ce and derived compositions in phosphors for white light LED, which in the last decade gave way to a new generation of solid-state lighting, see reviews Wu et al. (2007) and Ye et al. (2010) and references therein. Also a ceramic version of YAG Ce has been reported for such an application recently (Nishiura et al. 2011). Scintillation ceramics prepared from nanopowder precursors and...

Dy " can be also introduced into such a host. Ultrafine M5(P04)3F Dy (M = Ca, Ba) phosphors were prepared by way of combustion process. The PL excitation spectra show the excitation peaks observed at 250- 00 nm due to the f —> f transition of Dy " ion, which is useful for solid-state lighting purposes (i.e., mercury-free excitation). The PL emission of Dy " ion by 348-nm excitation gave an emission at 489 (blue), 582 (yellow), and 675 nm (red) [52, 53].
