Abstract
TiO$_2$ nanoparticles were prepared by photochemical synthesis in the dry toluene. The shape and size of the amorphous TiO$_2$ nanoparticles were investigated by transmission electron microscope. The particle size was varied by the contents of the titanium (IV) isopropoxide in dry toluene. Especially networked TiO$_2$ particles were formed from 40% titanium (IV) isopropoxide solution. The optical absorption spectra, photoluminescence, and PL excitation spectra of TiO$_2$ in dry toluene were obtained. The were shifted to the short wavelength as the contents of TiO$_2$ were increased. PL excitation had the peak at the wavelength regions is which the absorption increased steeply.
