title: Synthesis of CdSe and CdSe/TiO2 nanoparticles under multibubble sonoluminescence condition.
abstract: CdSe and CdSe/TiO(2) nanoparticles were synthesized under multibubble sonoluminescence (MBSL) condition. The influences of TiO(2) introduced as the sensitizer on the morphology and crystal transformation were investigated. The morphology, phase and optical properties of the final products have been characterized by X-ray powder diffraction, transmission electron microscope, UV-vis absorption spectroscopy and photoluminescence spectroscopy. The results showed that as-prepared nanoparticles are well-crystallized, and the suppression of crystal pattern transition as well as the control of CdSe crystal growth can be implemented by coupling of TiO(2) semiconductor. Furthermore, the possible growth mechanism for different morphologies and crystal phases of the nanocrystals were also discussed.
