Pt>i_xFexS nanoparticle films grown from acidic chemical bath

چکیده
Pbi_xFexS (x — 0:25, 0.50, 0.75) films were grown from an acidic chemical bath. Nanoparticle films were structurally characterized by XRD and TEM. Optical band gap of films is observed to vary from 1.65 to 1.42 eV with increase in their iron concentration from x — 0:25 to 0.75 in the films. Increased optical band gap of the ternary films compared to the estimated bulk value is attributed to quantum confinement in the nanocrystals deposited on solid substrates. PACS: 81.05.Hd; 81.05.Ys; 81.10.Dn

Study of Photo-Conductivity in MoS2 Thin Films Grown in Low-Temperature Aqueous Solution Bath
An experimental study over the optical response of thin MoS2 films grownby chemical bath deposition (CBD) method is presented. As two important factors, theeffect of bath temperature and growth time are considered on the photocurrentgeneration in the grown samples. The results show that increasing the growth time leadsto better optical response and higher difference betw...
متن کاملEffect of growth time on ZnO thin films prepared by low temperature chemical bath deposition on PS substrate
ZnO thin films were successfully synthesized on a porous silicon (PS) substrate by chemical bathdeposition method. X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM),and photoluminescence (PL) analyses were carried out to investigate the effect of growth duration(3, 4, 5, and 6 h) on the optical and structural properties of the aligned ZnO nanorods. T...
متن کاملChange of majority carrier type in PbS nanoparticle films
Change of majority carrier type from p to n in PbS semiconductor nanoparticle films grown from a solution bath has been achieved by applying an appropriate negative DC-bias to substrate during growth. This change is attributed to the observed decrease of sulfur content in the films which is accompanied by reduction in grain size on increasing the negative bias applied to the substrate. Pacs: 81...

Pbi-xCoxS ternary alloy films were grown using solution growth technique. X-ray fluorescence spectroscopy was used for compositional analysis. X-ray di9raction and atomic force microscopy analysis indicate the presence of nanometer-size grains in the films. Size dependence of optical band gap (Eg) is observed in the ternary nanoparticle films. Increase in Eg and decrease in DC-conductivity with...
