NANOMETRIC SURFACE DESIGN OF SIZE-QUANTIZED SEMICONDUCTOR MICROCRYSTALS

Semiconductor microcrystals (Q-particles), with diameters less that 10 0 Angstrom, modified with viologen have recently been produced. One po tential application for such particles would be for light energy conve rsion devices such as photocatalysts and photosensitizers in wet solar cells. The viologen moieties have the ability to function as electron mediators between the semiconductor and accepters in solution. The pr eparation and potential applications of these interesting materials ar e discussed.
