Transition metal dichalcogenide material (TMDM) Quantum Dot Engineering
Hybrid gold and graphene nanofeatures and quantum dots, carbon doped BN, MoS2 and WS2 quantum dots with average particle size of 1.9 nm, 3.6 nm, 3.3 nm and 3.9 nm respectively for graphene, MoS2, WS2, and BN were engineered ultrafast laser irradiation of precursor solutions. It is possible to tune the bandgap energy of the 2D materials quantum dots and emissive of QDs is shown. Here are some initial results of this work;
TEM images of (a)-(d) fabricated 2D materials Carbon doped quantum dots.
Recorded photoluminescence emission of fabricated QDs at different particle sizes and excitation wavelength.
