Abstract: In this paper we report the preparation of monodispersed lead sulfide ultrafine particles and their absorption spectra. The evident structures and blue shifts of the absorption spectra are observed. The results obtained are discussed by quantum size effect.

Key words: Ultraf ine particles, Quantum size effect, Surface modification
