Bright quantum-conÿned photoluminescence (PL) at visible wavelengths can be obtained from ultrathin-layer Si=SiO2 superlattices. We demonstrate that with the use of an optical resonator the PL peak wavelength and bandwidth can be modiÿed selectively. The strong enhancement and subsequent decrease in
