Abstract

In previous acticles, we have successfully synthesized the fabrication process of CdSe quantum dots (QDs) by colloidal method. The results, we obtained photoluminescence (PL) narrow, high absorption spectrum of the overall spectrum from ultraviolet to visible, the solution reaches a steady state well in three months. In this paper, we put the CdSe QDs on TiO2 films brought by dipping in a solution of CdSe. Through which we did carry TiO2 control by two parameters are temperature and time. The results were obtained for analysis of absorption spectra, luminescence spectra, we found that bring crystal optical properties of strongly dependent on temperature calculation, the thickness of films.... In addition, we also used biological agents 3- mercaptopropionic acid (MPA, COOH-R-SH) containing carboxyl groups and groups those with two purposes: The first one to do surface passivation of CdSe QDs, reducing the surface state and increasing the intensity of the luminescence spectra. The second MPA as a bridge between the CdSe QDs with TiO2 particles, help for the conversion of electrons into TiO2 is easier, can take advantage of the electron temperature. All the results obtained in order to guide for applications in solar cells to replace a photosensitive dye in the next research.
