✦ Synopsis

CdS quantum dots were prepared in @assfilms obtained from tetramethoxysilane (TMOS) or from tetraethoxysilane (TEOS) oftypical thickness of 0.1-0.2 pm. Diameters of the particles were evaluated from X-ray diffraction and from transmission electron microscopy and correlated with inflection points on the absorption spectra. The lowest quantum states are estimated and nonlinear optical properties measured.

Thin films of Al substituted cobalt ferrite layers on thermally oxidized silicon wafers were fabricated by a sol-gel method with various annealing temperatures. The structural and magnetic properties of the films were investigated with a X-ray diffractometer, a vibrating sample magnetometer (VSM) an
