The discovery of strong luminescence at room temperature from silicon cluster has attracted
an enormous attention in recent years due to its potential applications in Si-based …

Recent experiments searching for sub-GeV/c 2 dark matter have observed event excesses
close to their respective energy thresholds. Although specific to the individual technologies …

This chapter is extended to various electronical and optical modifications of amorphous
silica (a-SiO2) layers as they are applied in microelectronics, optoelectronics, as well as in …

Optical properties of silica glass with different doping of Al2O3 up to 1.5 mol% were studied.
Alumina stimulates creation of a luminescence centers with specific band at 3.3 eV. A new …

Photo-induced changes in GeO2 glass have been studied in terms of its optical and
structural properties. Band-gap excitation gives rise to modifications in mid-gap optical …

The main luminescent centers in SiO2 films are the red luminescence R (1.85 eV) of the non-
bridging oxygen hole center (NBOHC), a blue B (2.7 eV) band of the oxygen deficient …

The spectral and kinetic properties of excited states of luminescent defects (oxygen-deficient
centers) in SiO 2 ceramics are studied using pulsed cathodoluminescence and time …

This report estimates the potential for secondary emission processes induced by ionizing
radiation to result in the generation of quasiparticles in superconducting circuits. These …

Samples of two pure silica glasses have been investigated by high-power pulsed
cathodoluminescence as well as by synchrotron-photoluminescence and …

In this paper we present results of a low-temperature time-resolved photoluminescence (PL)
investigation of thin SiO2 films implanted with silicon ions. In addition to the luminescence of …
