The optical properties of polyvinylpyrrolidine (PVP) polymer have been enhanced using ternary Zn 1-x Sn x S as a filler for UVregion optical applications. Solution casting technique is used to prepare different Sn molar ratios (x: 0-0.3) in Zn 1-x Sn x S filled PVP polymeric composite films (1.0 wt.%). SEM, FT-IR and UV-visible-NIR spectrophotometry is utilized to characterize the optical properties of the plain PVP and polymeric composite films. SEM images reveal the homogeneous dispersion of the filler (Zn 1-x Sn x S) in the host PVP matrix. The FT-IR spectroscopic measurements ensure the successful interaction of ternary Zn 1-x Sn x S material and the host PVP polymer. The cut off transmittance edge is shifted from 260 nm (host PVP) to 390 nm (polymeric composite). The direct optical energy bandgap of the prepared polymeric composite films are shifted from 4.78 eV (plain PVP) to 3.45 eV for Zn 0.7 Sn 0.3 S polymeric composite film. An enhancement of the refractive index (n) and the optical conductivity (σ opt.) of the polymeric composite films is achieved as compared with those of the plain one. The single oscillator (E 0) and dispersion (E d) energies of the polymeric composite films were determined using Wemple and DiDomenico (WDD) model. The prepared polymeric composite films are strongly recommended for UV-region optical applications.

“…Transparent conductive oxide (TCO) films are essential component of the cells. CdO, [ 1 ] ZnO, [ 2 ] SnO 2 , [ 3 ] In 2 O 3 , [ 4 ] In:Al 2 O 3 , [ 5 ] Al:SnO 2 , [ 6 ] Gd:CdO, [ 7 ] and Cu/Ag:In 2 O 3 [ 8 ] are examples of pure oxide and metal‐doped oxide materials, which have been widely employed as window materials for many photovoltaic devices. Multicomponent oxides have gained a lot of attention as a new TCO material, which may control its electrical and optical properties by changing the ratio of cations.…”

SnO2–CdO (SCO) films and SnO2–CdO–In2O3 (SCIO) films are successfully deposited on Si (100) and glass substrates by radio frequency and direct current magnetron co‐sputtering. The films are characterized by X‐ray diffraction, scanning electron microscope, energy‐dispersive X‐ray spectroscopy, ultraviolet visible near‐infrared spectroscopy, and four‐point probes. SCO films exhibit Cd2SnO4 (011) preferred orientation, and the SCO film deposited at the sputtering power of 80W exhibits excellent crystalline quality and transmittance. The arrangement of clusters changes from sparse to dense when the indium element concentration increases. The resistivities of SCIO films are of two orders of magnitude lower than those of the SCO films. However, the visible light transmittances decrease slightly and the optical bandgap values decrease from 5.00 to 4.85 eV. The results indicate that the indium element plays an important role in improving the electrical properties of SCO films. SCIO films are expected to be a good candidate for transparent conductive films.

“…Thin film deposition technique plays a key role in the electronic and optical applications manufacturing. Various techniques have been used to deposit thin films, including sputtering [1], chemical vapor deposition [2], thermal evaporation [3], spray pyrolysis [4], dip-coating [5,6], electro-deposition [7] and spin coating [8]. As compared to other deposition techniques, spin coating is faster, easier, cheaper and need a small amount of depositing material [9].…”

In this work, a speed controlled, the programmable, low-cost, high-efficiency spin coating system is designed and implemented. The system is built from commercially available hard disk drivers DC motor, vacuum pump, speed sensor, brushless driver circuit carries Toshiba's TB6575FNG IC, PIC18F47J53 Microcontroller and using the interactive user interface to communicate with a user. Three different voltage stages and pulse width modulation techniques were used to guarantee accurate spinning speed and time. This system provides a wide range of precise and stable multi-step speeds rang of 1500 to 8,000 rpm. To evaluate the implemented system, ZnO thin films have been deposited by the sol-gel method on a glass substrate. Homogenous and uniform thickness films were obtained. The outstanding features of this system are the stability, accuracy, low energy consumption and durability, and the simplicity of adjusting multi-step spinning speed and time by using the interactive user interface.
