Colloidal quantum dot infrared lasers featuring sub-single-exciton threshold and very high gain
Nima Taghipour, Mariona Dalmases, Guy L. Whitworth +3
The use of colloidal quantum dots (CQDs) as a gain medium in infrared laser devices has been underpinned by the need for high pumping intensities, very short gain lifetimes and low…
On-Demand Activation of Photochromic Nanoheaters for High Color Purity 3D Printing
Alexander W. Powell, Alexandros Stavrinadis, Sotirios Christodoulou +2
The creation of white and multicoloured 3D-printed objects with high colour fidelity via powder sintering processes is currently limited by discolouration from thermal sensitizers…
