摘要：

Combining electron-beam lithography and electrochemical deposition, CdSe pillars can be fabricated in a specific shape and size in a well controlled manner. This simple technique provides an excellent opportunity to probe the change of optical properties of submicron structures due to size variation. Quite interestingly, it is found that the intensities of micro-photoluminescence as well as Raman scattering show an oscillatory behavior and can be enhanced at some particular diameters of CdSe pillars. This phenomenon can be well explained in terms of the resonant effects, in which the CdSe pillars can act as resonance cavities. Once the wavelengths of incident laser or the luminescence emitted from CdSe pillars are consistent with the predicted Fabry-Perot resonance, the optical properties can be greatly enhanced.
