Quantum Dot Optoelectronic Devices
High-performance semiconducting devices are synthesised chemically from nanomaterial and quantum dot colloids . These nanomaterials have energy applications in devices such as colloidal quantum dot solar cells ( CQDSCs ), solar windows , infrared photodetectors , and gas sensors . They are also highly luminescent materials with tuneable wavelengths / colours for security dyes , high brightness fluorescent coatings , quantum-enabled flat panel displays ( QLEDs ), and luminescent solar concentrators ( LSCs ). |
