Photoluminescence Properties of Nanocrystals
Description
The photoluminescence is a well-known physical phenomenon observed in many kinds of materials. Basically, it probably occurs when a specific solid absorbs photons (hν) with a particular wavelength (λ). After this excitation process, the recombination of the electron-hole pair in solid results in the emission of photons (hν΄) (lower energy than that found in the absorbed photons). In the last years, the photoluminescence of nanocrystals has been widely investigated because of its strategic importance for the technological development of optical devices, such as light-emitting diodes, lasers, sensors, scintillators, medical diagnostics, displays, electronic panels, and so forth.
This special issue of Journal of Nanomaterials aims to provide the readers with an overview on the latest achievements related to the photoluminescence properties of nanocrystals, mainly including synthesis methods, spectroscopic/microscopic characterizations, crystal growth, theoretical calculations, and models to explain the photoluminescence behavior. Moreover, theoretical studies based on the structure and photoluminescence properties will be also appreciated. Potential topics include, but are not limited to:
- Fundamental studies on the relation or effect between microstructure (shape, surface energy, or crystallographic orientation) and electronic structure (bands, density of states, charge density maps, etc.) and photoluminescence properties
- Structural characterizations: X-ray diffraction, transmission electron microscopy, Raman, infrared, X-ray photoelectron, and so forth
- Photoluminescence characterization: absorption, excitation, and emission spectra; room temperature and low temperature photoluminescence properties; new photoluminescence characterization methods or equipments
- Novel preparation of rare earth or semiconductor nanocrystals and their photoluminescence properties
