TL;DR: This work demonstrates multicolored narrow bandwidth emission from triangular CQDs with a quantum yield up to 54–72% and synthesizes these dots showing tunable emission color, high fluorescence and a narrow FWHM of only 30 nanometers, which will set the stage for developing next-generation high-performance C QDs-based light-emitting diodes.
Journal ArticleDOI
Bright Multicolor Bandgap Fluorescent Carbon Quantum Dots for Electroluminescent Light-Emitting Diodes.
TL;DR: In this paper, a multicolor bandgap fluorescent carbon quantum dots (MCBF-CQDs) from blue to red with quantum yield up to 75% were synthesized using a solvothermal method.
Journal ArticleDOI
53% Efficient Red Emissive Carbon Quantum Dots for High Color Rendering and Stable Warm White-Light-Emitting Diodes
TL;DR: An ultraviolet (UV)-pumped CQD phosphors-based warm white light-emitting diode (WLED) is realized for the first time and achieves a color rendering index of 97.
Journal ArticleDOI
Sulfur-Doped Graphene Quantum Dots as a Novel Fluorescent Probe for Highly Selective and Sensitive Detection of Fe3+
TL;DR: This novel fluorescent probe was successfully applied to the direct analysis of Fe(3+) in human serum, which presents potential applications in clinical diagnosis and may open a new way to the design of effective fluorescence probes for other biologically related targets.
Journal ArticleDOI
Noninjection Gram-Scale Synthesis of Monodisperse Pyramidal CuInS2 Nanocrystals and Their Size-Dependent Properties
Haizheng Zhong,Shun S. Lo,Tihana Mirkovic,Yunchao Li,Yuqin Ding,Yongfang Li,Gregory D. Scholes +6 more
TL;DR: The structure and surface studies showed that the resulting nanocrystals are pyramids of CuInS2 tetragonal phase with well-defined facets, while their surface is functionalized with dodecanethiol capping ligands, demonstrating quantum confinement effects in these systems.
