Advanced Materials Interfaces, EarlyView.Ba‐doped SrTiO3 perovskites establish a direct correlation between photoelectrochemical activity and photocatalytic performance. Optimized Ba0.5Sr0.5TiO3 exhibits enhanced charge separation, photocurrent generation, and visible‐light‐driven dye degradation through defect‐induced oxygen vacancies and lattice distortion.

Photoluminescence from surface-oxidized Ge nanoclusters
, 1998 Photoluminescence from gas-evaporated Ge nanoclusters consisting of a crystalline core encased in an oxide shell are presented. An as-grown sample shows room temperature luminescence with separate peaks around 357 and 580 nm.

Advanced Materials Interfaces, EarlyView.Zinc oxide thin films are engineered by controlling oxygen flow and nominal partial pressure during growth to tune atomic‐scale defects and crystallographic texture that limit device performance. By balancing competing defects, the films achieve improved preferential c‐axis orientation and enhanced ultraviolet photoresponse.

Remarks on Photoluminescence of Si Nanocrystals
It is a widely accepted opinion that the intense photoluminescence (PL) of Si nanocrystals (Si-nc) is caused by electron-hole recombination. It is also widely believed that the Auger recombination in Si-nc occurs only at collisions of one electron and ...

Advances in Halide Perovskites for Photon Radiation Detectors
Advanced Materials Technologies, EarlyView.This work highlights recent progress in perovskite‐based photon radiation detectors, covering organic–inorganic hybrid, inorganic, lead‐free double, and vacancy‐ordered halide perovskites. Their detection performance is compared, material‐specific advantages and challenges are examined, and provides insight into current limitations and future ...

Moldavian Journal of the Physical Sciences, 2019 The kinetics of a strongly nonequilibrium state of electrons and holes excited in quantum dots by a long laser pulse in the p-states are studied using time-resolved photoluminescence. Three bands of the transient photoluminescence spectra are identified,
