Study on Infrared Absorption Characteristics of Ti and TiNx Nanofilms
Infrared detector has a wide range of applications. To fabricate an IR detector with good sensitivity, an efficient IR absorber is needed. In this paper, we theoretically and experimentally investigated the absorption characteristics of Ti, multi-layer structured Ti-SiO2 and TiNx-SiNx nano films. The multi-layer structured TiNx-SiNx films with different nitrogen contents and Ti nano films with ...
متن کاملFinite Element Model for Atmospheric IR-Absorption
The updating concerns mainly the sensitivity analysis. The model is not anymore monochromatic, the system matrix K is now calculated separately for the two contributions water vapor and CO2 : K=KH2O+KCO2. The contribution of 0.04 % CO2 is small as compared to the contribution of 3.5 % water vapor: for the global and annual mean evacuation the contributions of CO2 and water vapor could be dealt ...
متن کاملMolecular Absorption
Remote sensing (from ground-, airplane-, balloon-, or satellite-based platforms) is a powerful and versatile tool to estimate profiles of atmospheric temperature, trace gases, etc. and has been established as indispensable for research on climate change, stratospheric ozone depletion etc. An essential prerequisite is the accurate and complete knowledge of the absorption properties of the atmosp...
متن کاملUncovering the mechanism for selective control of the visible and near-IR absorption bands in bacteriochlorophylls a, b and g
Bacteriochlorophylls (BChls) play an important role as light harvesters in photosynthetic bacteria. Interestingly, bacteriochlorophylls (BChls) a, b, and g selectively tune their visible (Qx) and near IR (Qy) absorption bands by the substituent changes. In this paper, we theoretically study the mechanism for the selective control of the absorption bands. Density functional theory (DFT) and time...
متن کاملAn IR absorption calibration for water in minerals
Using IR absorption data from polarized measurements on single-crystal minerals with stoichiometric water contents (in the form of H2O or OH groups in the structure), a linear calibration curve (r2 ø 0.98) for water in minerals is established in the form: ei (the integrated molar absorption coefficient in units of cm22 per mol H2O/L) 5 246.6(3753 2 n) (n 5 the mean wavenumber of the OH stretchi...
