Toward Efficient Orange Emissive Carbon Nanodots through Conjugated sp(2) -Domain Controlling and Surface Charges Engineering.
TL;DR: A strategy of achieving efficient orange emissive carbon nanodots (CNDs) with large sized conjugated sp(2) -domain is achieved in a solvothermal synthetic route using dimethylformamide as solvent.
Journal ArticleDOI
Long lifetime pure organic phosphorescence based on water soluble carbon dots
TL;DR: The observation of phosphorescence from carbon dots in a polyvinyl alcohol matrix is reported, attributed to C=O bonds on the surface of carbon dots and has a very long lifetime.

TL;DR: In this paper, temperature-dependent microphotoluminescence spectroscopy is conducted from 80-857 K. A surprisingly strong high-temperature photon emission is observed.
Journal ArticleDOI
Self-Powered Solar-Blind Photodetector with Fast Response Based on Au/β-Ga2O3 Nanowires Array Film Schottky Junction
Xing Chen,Kewei Liu,Zhenzhong Zhang,Chunrui Wang,Binghui Li,Haifeng Zhao,Dongxu Zhao,Dezhen Shen +7 more
TL;DR: A Au/β-Ga2O3 nanowires array film vertical Schottky photodiode is successfully fabricated by a simple thermal partial oxidation process and exhibits a very low dark current of 10 pA at -30 V with a sharp cutoff at 270 nm, which is much quicker than any other previously reported β-Ga 2O3-based photodetectors.
