Preparation and optical properties of CuO/SiO₂ nanocomposites

【摘要】 <正> Recently, much attention has been paid to the nonlinear properties because of theirpotential uses in optical functional devices, such as optical modulators, optical switches,fiber laser, and optical memories. Since Jain and Lind first reported high nonlinear opticalproperties of CdS_xSe_1-x quantum-dot doped glasses in 1983, nanometer semiconductormicrocrystals within glass matrix have been widely studied in which the electron and holeare quantum-confined by a deep potential well.更多还原
