Optical Studies on KBr:Tl and KCl-Br:Tl Mixed Crystals

E-Journal of Chemistry, 2010
Optical absorption spectra of KBr:Tl+ (0.0125 mol%) single crystals shows A, B and C bands around 258, 220 and 210 nm respectively. In KCl0.1Br0.9 :Tl+ (0.0125 mol%) mixed crystals exhibit slightly broadening of the A-band towards lower wavelength side ...

Investigation of band gap width in mixed ZnSxSe1–x crystals

Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2018
Scintillators based on ZnSxSe1–x are promising materials for X-ray and γ-ray detection. For optoelectronic devices, it is better to use semiconductor compounds with a direct-zone energy structure with its spectral range lying in the fundamental ...

Understanding the History of Two Complex Ice Crystal Habits Deduced From a Holographic Imager

Geophysical Research Letters, 2023
The sizes and shapes of ice crystals influence the radiative properties of clouds, as well as precipitation initiation and aerosol scavenging. However, ice crystal growth mechanisms remain only partially characterized.

Some effects of ice crystals on the FSSP measurements in mixed phase clouds [PDF]

Atmospheric Chemistry and Physics, 2012
In this paper, we show that in mixed phase clouds, the presence of ice crystals may induce wrong FSSP 100 measurements interpretation especially in terms of particle size and subsequent bulk parameters.

Partition between supercooled liquid droplets and ice crystals in mixed-phase clouds based on airborne in situ observations [PDF]

Atmospheric Measurement Techniques
The onset of ice nucleation in mixed-phase clouds determines the lifetime and microphysical properties of ice clouds. In this work, we develop a novel method that differentiates between various phases of mixed-phase clouds, such as clouds dominated by ...

Hollow Y zeolite single crystals: synthesis, characterization and activity in the hydroisomerization of n-hexadecane

Oil & Gas Science and Technology, 2019
Hollow Y zeolite single crystals have been obtained from a conventional NaY zeolite following a three-step process involving a severe dealumination of the zeolite with silicon tetrachloride (step #1), followed by an acid washing under mild conditions ...
