Diagnostics of inductively coupled chlorine plasmas : Measurement of Cl 2 ¿ and Cl ¿ densities
The absolute densities of positive ions ~Cl2 1 and Cl! are obtained over a 2–20 mTorr pressure range and 5–1000 W input radio-frequency rf power range in a transformer-coupled Cl2 plasma. The relative number density of Cl2 1 is measured by laser-induced fluorescence. These laser-induced fluorescence data are calibrated by Langmuir-probe measurements of total positive-ion density at low powers t...
متن کاملUltrafast excited-state dynamics of rhenium(I) photosensitizers [Re(Cl)(CO)3(N,N)] and [Re(imidazole)(CO)3(N,N)]+: diimine effects.
Femto- to picosecond excited-state dynamics of the complexes [Re(L)(CO)(3)(N,N)](n) (N,N = bpy, phen, 4,7-dimethyl-phen (dmp); L = Cl, n = 0; L = imidazole, n = 1+) were investigated using fluorescence up-conversion, transient absorption in the 650-285 nm range (using broad-band UV probe pulses around 300 nm) and picosecond time-resolved IR (TRIR) spectroscopy in the region of CO stretching vib...

متن کاملa novel method for preparation of alumina-supported rhenium-cesium catalyst, re-cs/-al2o3
alumina-supported cs3[re(c2o4)3] precursor has been synthesized for preparation of re-cs/g-al2o3 catalyst. cs3[re(c2o4)3] has been prepared from the reaction of recl3 with h2c2o4.2h2o and cscl in water. the complex has been characterized by elemental analysis and various spectroscopy techniques such as ft-ir, uv-vis and 13c-nmr. the complex was supported on γ-al2o3 by column chromatography. ...
متن کاملThe optoelectronic role of chlorine in CH3NH3PbI3(Cl)-based perovskite solar cells
Perovskite photovoltaics offer a compelling combination of extremely low-cost, ease of processing and high device performance. The optoelectronic properties of the prototypical CH3NH3PbI3 can be further adjusted by introducing other extrinsic ions. Specifically, chlorine incorporation has been shown to affect the morphological development of perovksite films, which results in improved optoelect...
