ZnO is an important II-VI semiconductor material for devices with possible applications such as piezoelectric transducers, gas sensors, transparent electronic in solar cell, saw devices. Based on known research, ZnO is the most promising in optoelectronic and optical applications, especially in UV region. An understanding of the optical properties of ZnO thin film on different substrates is als...

Thin film of zinc oxide was prepared by spin coating on pyrex glass using zinc acetate dehydrate, 2methoxyethanol and monoethanolamine (MEA) as a precursor, solvent and stabilizer respectively. Also, Aluminium-doped thin film of ZnO was prepared by using AlCl3. Deposited thin films were investigated for structural and optical properties using X-ray diffraction (XRD) and UV–VIS-NIR spectrophotom...

A highly transparent conductive film was fabricated using self-assembled silver electrodes with anti-reflection (AR) film. The micro pore diameter of sliver nanoparticles (ca 50~60nm in diameter) network electrodes expanded to size of 200-300 μm by the increase of air voids with evaporated water. The transmittance of the silver network electrode increased was drastically increased by the optica...

The response of the passive photodosimeter with halide film characterized by a high optical density of about 0.550 ± 0.007 was analysed on dose ranges, taking into consideration the filters of the dosimetric badge, and finally compared with the thermoluminescent dosimeter (TLD). In this respect the dosimeters were exposed to a Cs 137 calibration radioactive source at different points within (0....

We investigate the optical and thermo-optical properties of amorphous TiO2–Al2O3 thin-film bilayers fabricated by atomic layer deposition (ALD). Seven samples of TiO2–Al2O3 bilayers are fabricated by growing Al2O3 films of different thicknesses on the surface of TiO2 films of constant thickness (100 nm). Temperature-induced changes in the optical refractive indices of these thin-film bilayers a...

Gafchromic XRCT radiochromic film is a self-developing high sensitivity radiochromic film product which can be used for assessment of delivered radiation doses which could match applications such as computed tomography (CT) dosimetry. The film automatically changes color upon irradiation changing from amber to dark greenish-black depending on the level of exposure. The absorption spectra of Gaf...

An optical model based on classical electrodyanmics has beeb exploited to simulate the optical effects for the top-emitting organic light emitting diodes. The optical performance of the devices can be obtained through calculation of the power density in each planar thin film. The far field emission profile and spectrum are derived base on this model. Predicated optical performance is compared w...
