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

open access: yesE-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 ...

The Artificial Mixed Fused Quartz Particles and Silicon Particles-Assisted High-Performance Multicrystalline Silicon

open access: yesCrystals, 2019
Mixed seeds of fused quartz particles and silicon particles were laid at the bottom of the crucible to assist the growth of multicrystalline silicon crystals. The full melting process was used, and then we found that the grown crystals had higher quality.

Sensitivity of Mixed-Phase Cloud Optical Properties to Cloud Particle Model and Microphysical Factors at Wavelengths from 0.2 to 100 µm

open access: yesRemote Sensing, 2021
The representation of mixed-phase cloud optical properties in models is a critical problem in cloud modeling studies. Ice and liquid water co-existing in a cloud layer result in significantly different cloud optical properties from those of liquid water ...

Investigation of band gap width in mixed ZnSxSe1–x crystals

open access: yesTekhnologiya 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

open access: yesGeophysical 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.

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

open access: yesAtmospheric 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

open access: yesOil & 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 ...
