Abstract
This paper describes the control of the quantum size effect by controlling the coating layer thickness in TiO2–SiO2 core-shell hybrid particles obtained by the liquid phase deposition (LPD) method. The coating layer thickness of TiO2 on SiO2 nano-particles was controlled by changing the [Ti]/[Si] ratio. The titania coating thickness and crystallite size were estimated by transmission electron microscope (TEM) and X-ray diffraction (XRD), respectively. The quantum size effect of the obtained nano-hybrid particles was estimated by the band gap energy shift, using ultraviolet-visible spectroscopy (UV–vis). As a result, we successfully controlled the degree of the quantum size effect by controlling the coating layer thickness in core-shell TiO2–SiO2 hybrid particles.
