Abstract

Zeolites are ideal host material for generation and stabilization of regular ultrasmall quantum dots (QDs) array with the size below 1.5 nm. Quantum dots (QDs) with high density and extinction absorption coefficient have been expected to give high level of third-order nonlinear optical (3rd-NLO) and to have great potential applications in optoelectronics. In this paper, we carried out a systematic elucidation of the third-order nonlinear optical response of various types of QDs including PbSe, PbS, CdSe, CdS, ZnSe, ZnS, Ag2Se, and Ag2S by manipulation of QDs into zeolites Y pores. In this respect, we could demonstrate that the zeolite offers an ideal platform for capability comparison 3rd-NLO response of various types of QDs with high sensitivities.
