A Theoretical Study on Laser Cooling Feasibility of Group IVA Hydrides XH (X = Si, Ge, Sn, and Pb): The Role of Electronic State Crossing [PDF]

open access: yesFrontiers in Chemistry, 2020
The feasibility of direct laser cooling of SiH, GeH, SnH, and PbH is investigated and assessed based upon first principles. The internally contracted multi-reference configuration interaction method with the Davidson correction is applied.

Computational Study of the Photophysical Properties and Electronic Structure of Gold (III) Complexes with Different Groups [PDF]

open access: yesChemistryOpen
A series of novel delayed phosphorescent gold(III) complexes, Au(EDG)(EAG) (where EDG = electron‐donating group and EAG = electron‐accepting group), have been reported, exhibiting stable and high‐performance luminescence. The thermally stimulated delayed

Toward Bright Polymetallic Biopolymer-Protected Luminescent Nanoclusters [PDF]

open access: yesMolecules
Polymetallic nanoclusters (NCs) offer a powerful route to brighter and more tunable luminescent materials, while biopolymer ligands provide additional advantages for sensing and bioimaging. However, the mechanisms responsible for luminescence enhancement

Excellent Ultracold Molecular Candidates From Group VA Hydrides: Whether Do Nearby Electronic States Interfere?

open access: yesFrontiers in Chemistry, 2021
By means of highly accurate ab initio calculations, we identify two excellent ultracold molecular candidates from group VA hydrides. We find that NH and PH are suitable for the production of ultracold molecules, and the feasibility and advantage of two ...

Elucidating complex triplet-state dynamics in the model system isopropylthioxanthone

open access: yesiScience, 2022
Summary: We introduce techniques for probing the dynamics of triplet states. We employ these tools, along with conventional techniques, to develop a detailed understanding of a complex chemical system: a negative-tone, radical photoresist for multiphoton

Magnetic-field modulation of topological electronic state and emergent magneto-transport in a magnetic Weyl semimetal

open access: yesThe Innovation, 2023
The modulation of topological electronic state by an external magnetic field is highly desired for condensed-matter physics. Schemes to achieve this have been proposed theoretically, but few can be realized experimentally.

Investigation of the spin-forbidden process in thymine [PDF]

open access: yesHemijska Industrija, 2012
The intersystem crossing rate from the lowest singlet to the lowest triplet state of thymine was studied by means of the ab initio methods. The rate was calculated employing the time-dependent approach based on the correlation function.

Effect of temperature on rate of the spin-forbidden transition in uracil and thymine [PDF]

open access: yesJournal of the Serbian Chemical Society, 2013
The intersystem crossing rates of uracil and thymine molecules in interaction with the heat bath were studied by means of the ab initio methods. The rates were calculated employing the time-dependent approach based on the correlation function.
