Abstract

The thermo-optic properties of CdSe/ZnS quantum dots (QDs) are investigated in this paper. Two CdSe/ZnS QDs-doped samples are fabricated and the closed aperture Z-scan data were obtained by a single-beam Z-scan setup with a continuous laser as the exciting source. With the measured curves the coefficient of nonlinear refractive index n2 (caused by thermal effect) and the thermo-optic coefficient were achieved. CdSe/ZnS QDs-doped materials show larger thermooptic coefficients than the glass materials by 2 orders of magnitude.
