We have used aqueous dispersions of silver nanowires to prepare thin, flexible, transparent, conducting films. The nanowires are of length and diameter close to 6.5 μm and 85 nm, respectively. At low thickness, the films consist of networks but appear to become bulk-like for mean film thicknesses above ∼160 nm. These films can be very transparent with optical transmittance reaching as high as 9...

Films of optical quality suitable for waveguide and optical device elements have been designed and growth processes developed for producing such films. Films with various compositions and thicknesses have been prepared by chemically depositing GaAs and Ga.. .AL As upon GaAlAs and GaAs. Film thicknesses from 2 to 17 urn and compositions from x = 0.02 to x = 0.25 (Ga. Al As) were obtained. Techni...

Abstract: Different thickness of Cu2S thin films were prepared by vacuum evaporation under a pressure of 10-6 torr at an evaporation rate of 3Å /sec. Cu2S has direct band gap energy and indirect band gap energy at 1.2eV and 1.8 eV respectively. This paper presents the analysis of structural and optical properties of the Cu2S thin film by X-ray diffractometer (XRD) and UV-Vis-NIR Spectrophotomet...

The response curves and sensor properties of silver-deposited optical fibers with Ag film thicknesses of 20.0 - 80.0 nm based on surface plasmon resonance (SPR) were investigated. The response of the Ag-deposited optical fiber sensor depends on the thickness of the Ag film. The Ag-deposited optical fiber sensors show higher responses than those deposited with Au. The reflection properties of Ag...

We have investigated the possibility of determining the optical coefficients of muscle in the extremities with in vivo time-resolved reflectance measurements using a layered model. A solution of the diffusion equation for two layers was fitted to three-layered Monte Carlo calculations simulating the skin, the subcutaneous fat and the muscle. Relative time-resolved reflectance data at two distan...

AIM We investigated the relationship between a new index considering the estimated working space and difficulty of robot-assisted radical prostatectomy (RARP) using our database. PATIENTS AND METHODS Working height was calculated by the obstetric conjugate diameter minus the bladder and rectal wall thicknesses minus the thickness of postvesical fat minus the rectal fat thicknesses measured us...

OBJECTIVES Optical coherence tomography, an imaging modality using near-infrared light, produces cross-sectional tissue images with a lateral pixel resolution of 10 microm. However, normative data is first needed on epithelial thickness for lesion characterisation, and, to date, little exists. The purpose of our study is to measure normal laryngeal epithelial thickness by in vivo optical cohere...

STATEMENT OF THE PROBLEM Optical properties of the composite resins, concerning their translucency and thickness, are affected by discolored tooth structure or inherent darkness of the oral cavity. PURPOSE This study aimed to compare the translucency parameter (TP) of five different composite resins in different thicknesses and to evaluate their masking ability in black backgrounds. MATERIA...

ABSRTACT: To increase the photon transmission in solar cells based on multicrystalline silicon, two different double layer antireflections (DARC1 and DARC2) were optimized and simulated, to optimize the antireflection double layer, we have developed a numerical simulation code with Matlab software package where we have used the method of transfer matrix to solve the optical equation. These solu...
