We report a hybrid system based on conducting polymer-semiconductor from poly(otoluidine) (POT) doped with camphor sulfonic acid(CSA) and cadmium selenide capped with Tri sodium citrate(CdSe-TSC) by the physical mixing method. The influence of CdSe nanoparticles weight percent on the hybrid thin films have been investigated by means of XRD, FESEM, UV-VIS absorption and photoluminescence spectroscopy (PL) measurements. The main diffraction peaks of POT/CdSe hybrids are analogous to the neat CdSe nanoparticles. The absorption measurement reveals that the interaction between CdSe and POT in the hybrid materials led to the blue shift and broadening of the polaron absorption band. The energy gap has been decreased with an increase in the concentration of CdSe NPs. the PL intensity has been totaly quenched when the tow materials are bring to other. The hybrid nanocomposite material and provides useful evidence apropos the optimum use of CdSe nanoparticles in conductive polymer based optoelectronics.

An attempt is made to resolve the controversy related to the reconstruction mechanism of magneto-optical stannite/kieserite crystal structure with a random mixture of two quaternary compounds of Cu2ZnSnS4-Cu2FeSnS4 while the identification of phase formation by XRD is difficult. Since the Fe is surprisingly emerged on the Cu position while Fe is replaced by Zn. The induced dynamical sliding by Cu-ionic-host could be existed which is strongly consequence of magnetic exchange competition (F.M and AFM) through the thermos remanent magnetic reflected on DTA thermal loop. Towards the distortion of intra-plane “a-b”, the volume unit cell and c/a are decreased to minimize Gibbs free energy where the band gap energy is also decreased. The broad maximum of Raman spectroscopy is almost decreased linearly. A strong competition between F.M and AF.M due to the distribution of exchange interaction are evident in x≤0.5 which is dominated by AF.M on x=1.
