SnSe2 is an anisotropic binary-layered material with rich physics, which could see it used for a variety of potential applications. Here, we investigate the gas-sensing properties of SnSe2 using first-principles calculations and verify predictions us

We studied the effect of europium (Eu) doping on the near band edge emission of ZnO thin films, fabricated by sputtering and high temperatures annealing. The doping concentration of Eu in the ZnO films was varied from 0.01 to 0.62 at.%. Photoluminesc

Graphene is a single layer of carbon atoms with a large surface-to-volume ratio, providing a large capacity gas molecule adsorption and a strong surface sensitivity. Chemical vapor deposition-grown graphene-based NO2 gas sensors typically have detect

GeSn is a group IV alloy material with a narrow bandgap, making it favorable for applications in sensing and imaging. However, strong surface carrier recombination is a limiting factor. To overcome this, we investigate the broadband photoelectrical p

In this work, we have investigated the effects of ytterbium (Yb) doping concentration on the structure and near band-edge (NBE) photoluminescence (PL) of ZnO thin films on Si after high temperature annealing. The films were made by magnetron sputteri

We studied the photoluminescence (PL) properties of (Ce + Yb) co-doped ZnO thin films as a function of high temperature annealing. The films were fabricated by magnetron sputtering. After 1000-1100°C annealing, the near band edge (NBE) emissions of

We report on photoluminescence (PL) properties of europium (Eu) and ytterbium (Yb) co-doped silicon-rich oxide films with different Si excess and after various annealings. The dominating PL signal of Eu changed gradually from that of Eu3+ ions to Eu2

We report on the photoluminescence (PL) properties of europium (Eu) and ytterbium (Yb) co-doped SiO2 thin film. The Eu (both Eu2+ and Eu3+) PL and the Yb3+ PL is co-related under different temperature annealing. However, upon 1100°C anneal, the Eu P
