| Abstract: | Quantum size effects and optical properties of PbS semiconductor ultrafine particles as well as the influence of the surrounding dielectric environment on their optical properties were investigated. It was found that the surface defects were effectively removed and the luminescence intensity of the particles was enhanced by surface modification. Experimental results are discussed with the tight-binding model. |

| Keywords: | ultrafine particle quantum size effect surface modification |
