White light emission based on semiconductor nanostructures represents a new technology platform for solid state lighting. The major advantages are the easy synthesis and tuning of color emission in the visible range and the high optical stability of nanostructures. This chapter summarizes the materials that can be used as white light nanophosphors.
Bi2SiO5:Yb3+,Er3+ yolk–shell nanophosphors have been successfully synthesized, which are expected to find important applications in optical thermometry and solid-state lighting.
