Abstract: Samples of DBS modified PbS nanoparticles doped in ORMOSIL were prepared by Sol Gel method and characterized The HRTEM demonstrated that the sizes of PbS nanoparticles are 3~4nm and that the particles separately and homogeneously disperse in the ORMOSIL The blue shift of the absorption edge shows an obvious quantum size effect.

Key words: ORMOSIL, PbS nanoparticle, quantum size effect
