  Optical properties of potassium-doped polyacetylene Author links open overlay panel D.B. Tanner a G.L. Doll b 1 A.M. Rao b 2 P.C. Eklund b 3 Cited by: The optical reflectance of polyacetylene doped with high concentrations of potassium has been measured, and the optical properties esti-mated by Kramers–Kronig analysis. The samples, doped by a vapor-phase technique to y ≈ and , showed strong doping-induced infrared absorption at ∼, , and cm−1. These experiments. Optical sensors fabricated in zeolite nanoparticle composite films rely on changes in their optical properties (refractive index, n, and thickness, d) to produce a measurable response in the presence of a target analyte. Here, ellipsometry is used to characterize the changes in optical properties of Linde Type L (LTL) zeolite thin films in the presence of Cu2+ ions in solution, with a view to. The nonlinear refractive index n 2 is an important parameter for the nonlinear optical properties of a medium. This study primarily targets to measure the third-order nonlinear optical properties of potassium dihydrogen phosphate (KDP) and deuterated potassium dihydrogen phosphate (DKDP) with 70% deuteration content at λ = nm using the Z-scan technique.

The optical properties of potash doped lead chloride (PbCl 2) have been studied by sol gel technique. The optical properties of the materials were determined using a JENWAY UV-VIS. Abstract. We present a detailed study of the absolute Doppler-broadened absorption of a probe beam scanned across the potassium D lines in a thermal vapour. Spectra using a weak probe were measured on the 4S!4P transition and compared to the theoretical model of the electric susceptibility detailed by Zentile et al () in the code named ElecSus. window. The presence of potassium in the crystal has been confirmed by mass spectrometry. The percentage composition of potassium in L-histidine acetate with potassium nitrate was established by inductively coupled plasma (ICP) technique. Key words: LHA, potassium nitrate, FTIR, UV – Vis NIR, optical transmission. INTRODUCTION. Modelling the response of potassium vapour in resonance scattering spectroscopy 2 1. Introduction Resonance scattering techniques are often used to study the properties of atoms and molecules, such as energy levels and the ne and hyper- ne structure [1]. When applied to absorp-tion spectroscopy with techniques such as op-Author: S J Hale, W J Chaplin, G R Davies, Y P Elsworth.

Some studies of aerosol optical properties have been made in southern and central China (L. C. Tao et al., b), and those at remote and rural sites in China provide information on regional. Mahadevan M, Ramachandran K () Crystal growth, structural, thermal and optical properties of potassium para-nitrophenolate dihydrate semi organic single crystal for NLO application. International Journal of Innovative Research in Science, Engineering and Technology 3 (1): pp. – The study about optical properties of KTN films is also one of the investigative hotspots, and the optical and nonlinear properties have been reported previously,,. However, rare studies about refractive index dispersive behavior have been by: The dielectric constant of potassium is determined from eV to eV by using only s -polarized ε 1 -spectrum is expressed by (λ/) 2 in λA. The ε 1 - and ε 2 -spectra are compared with the other published data, and discussed with the sum rule and the dispersion loss function is separated from the absorption Cited by:
