A MXene Quantum Dot is a type of quantum dot that is derived from two-dimensional MXene compounds, known for their unique electronic and structural properties, making them suitable for applications in metal ions sensing and bioimaging due to their ultrathin thickness, high stability, and superior...
For producing different relative humidity (RH) environments, we bubbled saturated aqueous solutions of different salts (potassium carbonate, cobalt chloride and potassium sulfate, for generating RH = 43%, 64% and 97%, respectively) in a closed glass vessel, under a constant temperature (25 ...
(a) A schematic illustration of a Schottky photodiode structure for the substrate-free photodetector. The layers from bottom to top are aluminum back contact (grey), ultrathin QD-nanocellulose active layer (purple), and semi-transparent gold electrode (yellow). (b) A band diagram of the ...
A similar mechanism for the EQE roll-off has been previously shown to be operative in traditional LEDs based on epitaxial quantum-well emitters18,19. Consideration of the band-diagram of our LEDs along with the results of spectroscopic studies of carrier dynamics suggest that QDs in these ...
