Abstract

The CdSe nanocrystal quantum dot (NQD) titania nanocomposite with semiconductor filling factors as high a 20%, refractive indices as large as 2.1, and quantum yield (QY) greater than 10% at room temperature, fabricated using dots without inorganic overcoating was reported. As such, the nonlinear optical and optical gain performance of these new materials was extensively studied. Such studies indicated high magnitudes for both the third-order non-linear susceptibility and the modal gain, comparable to those values obtained for close-packed, self-assembled films.
