Measurements of photoluminescence (PL) from composites of silica nanoparticles (the
primary particle size 7 and 15 nm) as a function of heat treatment temperature show that the …

Abstract The photoluminescence (PL) from 7-and 15-nm silica (SiO 2) nanoparticles induced
both by ArF laser light [λ exc= 193 nm (6.4 eV), τ L= 15 ns] and by Nd: YAG (yttrium …

The optical properties of point defects are frequently the most important parameter in
applications of glassy silica. They are relatively easy to measure on standard …

Photoluminescence (PL) from composites of 7-and 15-nm silica (amorphous SiO 2)
nanoparticles and bulk type-III fused silica induced by two-photon band-to-band excitation …

Thermally grown SiO2 layers of thickness d= 500 nm have been implanted by Ge+, Si+, and
O+ ions of energy 350, 150, and 100 keV, respectively, and a uniform implantation dose of …

We investigated the red luminescence in a porous film of silica nanoparticles, originating
from surface nonbridging oxygen hole centers. The excitation spectrum was measured from …

The luminescence of the self-trapped exciton (STE) in SiO2 films was measured at low
temperatures on the background of defect luminescence under cathodoexcitation and …

Aiming at the fabrication of elastomeric organic scintillators for the detection of ionizing
particles and neutrons with good light yield, mechanical robustness and radiation …

The cathodoluminescent and photoluminescent properties of the nanoporous silica frustules
of various diatom strains and of natural diatom samples are presented. The spectra are …

Transmission electron microscopy is an excellent experimental tool to study the interaction
of free electrons with nanoscale light fields. However, up to now, applying electron …
