The reversible charging of multiple layers of nanocrystals...

at room temperature has been achieved by using a simple, solid-state device. This reversible charging leads to the possibility of using nanocrystals (NCs) in optical modulators and in tunable fluorescent or photochromic displays. These structures should also allow systematic studies of the photophysics of charged NCs. (M. G. Bawendi et al., August 5, Adv. Mater. 2002, 14, 1068-1071)
