Gain-switching in CsPbBr3 microwire lasers

Communications Physics, 2022
Gain-switching techniques offer a route to ultrafast lasing at the microscale. Here, 13 ps single-mode lasing from inorganic perovskite CsPbBr3 microwires is demonstrated and low transient saturated gain is identified as a significant limitation for ...

Large-area straight, regular periodic surface structures produced on fused silica by the interference of two femtosecond laser beams through cylindrical lens

Opto-Electronic Advances, 2021
Inhomogeneity and low efficiency are two important factors that limit the application of laser-induced periodic surface structures (LIPSSs), especially on glass surfaces.

A novel fluorescent sensor for diammonium and metal ions based on a supramolecular charge-transfer complex of bis(aza-18-crown-6)-containing dienone

Frontiers in Chemistry, 2023
A bis(aza-18-crown-6)-containing 2,5-di(benzylidene)cyclopentanone and a bis(ammoniopropyl) derivative of 1,2-di(4-pyridyl)ethylene in MeCN were found to form a supramolecular charge-transfer complex, which can act as an “off–on” fluorescent sensor for ...

Electron-impact spectroscopy [PDF]

Discussions of the Faraday Society, 1963
A spectrometer has been devised for determining electronic energy levels of molecules by inelastic scattering of low-energy electrons. It permits the detection of optically forbidden electronic transitions as clearly as optically allowed ones in a routine manner.

Ultrafast photoinduced dynamics of a donor-( $$\mathrm \pi$$ π )bridge-acceptor based merocyanine dye

Scientific Reports, 2022
Merocyanine dyes are of great interest amongst researchers due to their nonlinear optical (NLO) properties and solvatochromism. Molecular structure of these dyes constitutes conjugated pathway between the donor and acceptor substituents, with lowest ...

CARTESIAN AXIS AND PLANE CONVENTIONS IN Cnv SYMMETRY GROUPS

Química Nova, 2021
In this work, we call the attention to the ambiguity found in the literature when labeling vibrations and molecular orbitals as B1 and B2 for molecules belonging to the C2v point group as, for example, the water molecule.
