Samples of SiC ceramics differing in porosity in the range 1–9% were damaged by a falling weight, and the fractoluminescence (FL) activity lasting up to 0.4 ms was detected with the time resolution of 10 ns. The recorded time series of the light em

Time series of acoustic emission pulses were excited in ductile ZnS and ZnSe ceramics either by a falling weight or by indenting the Vickers pyramid. Energy distributions in emitted acoustical emission pulses were found to be random (Poisson-like) in

A set of heterogeneous and homogeneous materials differing in their brittle and ductile characteristics (granite, marble, silica ceramics, silicon carbide, organic glass) were subjected to impact damaging by a falling weight. Multiple chemical bond

Accumulation of microcracks in response to point impact damage in MgAl2O4 ceramics doped with Cr3+ ions has been studied using acoustic emission measurements. The results demonstrate that the maximum crack length at a higher chromium concentration in

We obtained a Raman spectrum for a surface layer of porous carbon ceramic (porosity ≈5%) of ≈80 nm thick. The analysis of the spectrum showed that the ceramics contain crystals of silicon carbide 6H‑SiC and silicon. The destruction of ceramics

The mechanisms of radiative recombination and electroluminescence in the structures based on the films of perovskite nanocrystals CsPbBr3 in the matrix of a semiconductor polymer MEH-PPV have been considered. It has been shown that two mechanisms det

It is found using triboluminescence (TL) that nanocrystals of silicon (ncSi) with linear dimensions of about 4 nm are formed from a single crystal of silicon (Si) under friction. The time dependence of the intensity of TL signals is investigated. It

Mechanoluminescence (ML) from deformed ductile materials is caused by sliding of charged dislocations. The main source of the ML in loaded brittle solids is the interatomic bond breakage. In this work, the ML from impact damaged ductile ZnS ceramics
