- Determining the mechanism of electrodynamic interactions and charge transfer processes in metal-dielectric or metal-semiconductor nanocomposite materials with planar nanostructures arranged in a partially ordered manner with high density.

Successfully synthesized sustainable and environmentally friendly Ag@CQDs nanocomposites using plasma-assisted techniques and natural precursors derived from oranges. The structure, morphology as well as optical properties of the fabricated Ag@CQDs nanocomposites were evaluated, showing their potential applications in many fields in the future.
- The size-dependent optical properties and radiative lifetimes of cubic CdSe zincblende nanocrystals (NCs) with diameters ranging from 3.4 to 5.5 nm were investigated. Our findings confirm that the band gap increases with decreasing NC size, consistent with the principles of quantum confinement, and the strong correlation between optical measurements and TEM data strengthens the reliability of our calibration curves for accurate size determination from absorption and emission spectra.
-The spectral properties of layered Ag/CuPc nanocomposites prepared by thermal evaporation in vacuum were investigated. It was found that the bands due to SPR absorption were stronger for systems with thin CuPc interlayers (10 nm). However, the spectral absorption was more evenly distributed for systems with thicker CuPc interlayers (20 nm). The long-wavelength shift of the SPR absorption band was observed as the thickness of the CuPc interlayer decreased. At the same time, the results also showed that with relatively low annealing temperature (~200°C) can significantly affect the spectral and morphological properties of the silver nanostructures, the studied samples, both the original and the annealed samples, have high resistivity.
- Numerical simulation results show that the attenuated absorption spectrum of the hybrid metal-organic nanostructures, as well as the near-field effects at the spectral range of the absorption bands of the organic component, can be tuned by changing the plasmonic nanoparticle material, size or refractive index and shell thickness.
During the project implementation, we had specific scientific exchanges with foreign partners. The results of the project make a great contribution to training human resources in the field of quantum optical physics and nanophotonics in Vietnam as well as strengthening cooperation and joint scientific publication.

The results of this research have contributed greatly to the training of young scientists in the field of quantum photonics and nano-photonics in Vietnam. It also promoted international publications, which is now a matter for the Vietnamese Academy of Science and Technology.
