Integration of superconducting nanowire single-photon detectors with nanophotonic
waveguides is a key technological step that enables a broad range of classical and quantum …

This paper reviews what is known about the structures and optical properties of point defects
in silica glass and other amorphous forms of SiO2. The available structural information …

High‐performance organic solar cells (OSCs) at the current stage are majorly accomplished
from the processing of halogenated solvents, such as chloroform, which will be constrained …

The spectroscopic properties, structure and interconversions of optically active oxygen-
deficiency-related point defects in vitreous silica are reviewed. These defects, the E …

Silicon quantum dots (SiQDs) hold great promise for many future technologies. Silicon is
already at the core of photovoltaics and microelectronics, and SiQDs are capable of efficient …

Crystalline silicon is the most important semiconductor material in the electronics industry.
However, silicon has poor optical properties because of its indirect bandgap, which prevents …

We report large-scale synthesis of silica nanowires (SiONWs) using an excimer laser
ablation method. Silica was produced in the form of amorphous nanowires at a diameter …

Luminescence centers causing optical absorption bands in the 5 eV region in oxygen-
deficient pure ('Si-doped'), as well as in Ge-and Sn-doped glassy SiO 2 were studied. The …

The current controversy over the nature of the centers giving rise to the 1.9 eV
photoluminescence (PL) band (the R-band), the suggested defect models and the relevant …

Abstract Photoluminescence under 7.9-eV excimer-laser excitation was measured at room
temperature on various types of high-purity silica glasses, which were classified based on …
