Synthesis and Study of Optical Characteristics of Ti(0.91)O(2)/CdS Hybrid Sphere Structures

The optical properties of alternating ultrathin Ti(0.91)O(2) nanosheets and CdS nanoparticle hybrid spherical structures designed by the layer-by-layer (LBL) assembly technique are investigated. From the photoluminescence (PL) spectral measurements on the hybrid spherical structures, a spectrum-shif...

description The optical properties of alternating ultrathin Ti(0.91)O(2) nanosheets and CdS nanoparticle hybrid spherical structures designed by the layer-by-layer (LBL) assembly technique are investigated. From the photoluminescence (PL) spectral measurements on the hybrid spherical structures, a spectrum-shifted fluorescence emission occurs in this novel hybrid material. The time-resolved PL measurements exhibit a remarkably increased PL lifetime of 3.75 ns compared with only Ti(0.91)O(2) spheres or CdS nanoparticles. The novel results were attributed to the enhanced electron-hole separation due to the new type II indirect optical transition mechanism between Ti(0.91)O(2) and CdS in a charge-separated configuration. ELECTRONIC SUPPLEMENTARY MATERIAL: The online version of this article (10.1186/s11671-018-2488-3) contains supplementary material, which is available to authorized users.
