摘要：

Excitation profiles of resonant second-harmonic and hyper-Raman scattering in a CdS quantum-dot system are reported. Two maxima have been found in the related two-photon excitation spectra near the fundamental absorption region. Relative to the one-photon absorption spectrum, the maxima are more pronounced and shifted in energy. The result has revealed quantum-confined electron-hole pair states with a total angular momentum of odd number. Effective masses in the quantum dots have been estimated.
