Cadmium selenide nanoparticles were prepared in aqueous medium using sodium selenite as the selenium source. Thioglycolic acid was used as the ligand to stabilize the particles. The synthesized particles were surface modified by 1-dodecanethiol (1-DDT) to transfer the particles from aqueous to organic medium in the presence of acetone.  The surface modified particles were finally blended with poly-3-hexyl-thiophene (P3HT)  polymer in chloroform. The blends were infiltrated into the TiO2 nanotubes through heating assisted method in dichlorobenzene. TiO2 nanotubes were prepared by electrochemical anodization technique in the presence of a hydrogen fluoride (HF). The prepared particles and the CdSe/P3HT infiltrated nanotubes were analysed using UV-Visible, SEM,TEM, AFM and FT-IR. The increased absorption was observed through UV-Visible spectra for infiltrated TiO2 nanotubes with CdSe/P3HT blends. TEM analysis shows that the prepared particles are spherical in nature. SEM images reveal the pore size of the TiO2 nanotubes and the infiltration of P3HT polymer into the nanotubes.  AFM images further confirm the morphological changes due to the P3HT after infiltration. FT-IR spectra show the corresponding bands of the polymer which ensures the incorporation into the tubes. The results are discussed in detail.
