In this paper, PbS semiconductor quantum dots (QDs) with near-infrared (NIR) photoluminescence were synthesized in oleic acid and paraffin liquid mixture by using an easily handled and 'green' approach. Surface functionalization of the QDs was accomplished with a silica and

A lot of interesting and sophisticated examples of nanoparticle (NP) self-assembly (SA) are known. From both fundamental and technological standpoints, this field requires advancements in three principle directions: (a) understanding the mechanism and driving forces of three-dimensional (3D) SA with

MCM-41 molecular sieve coupled with lead sulfide quantum dots (PbS-MCM-41) was prepared by ion-exchange method. The photocatalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-vis spectroscopy, infrared spectroscopy (IR) and BET (Brunauer-Emmett-Teller) experiments. Exciton absorption peak at
