Excited state localisation cascades in inorganic semiconductor nanoparticles.

Rare Earth Doped Nanoparticles in Organic and Inorganic Host Materials for Application in Integrated Optics

The preparation and the optical properties of lanthanum fluoride (LaF3) nanoparticles doped with erbium and neodymium will be discussed. Organic and inorganic materials in the form of polymers and sol-gels were used to serve as the hosts for the inorganic nanoparticles, respectively. The organic host material has been synthesized such that it is photo-crosslinkable to facilitate straightforward...

Photoluminescence in semiconductor nanoparticles; an atomistic view of excited state relaxation in ZnS

Quantization of electromagnetic fields in the presence of a spherical semiconductor quantum dot and spontaneous decay of an excited atom doped in this nanostructure

In this paper we consider electromagnetic field quantization in the presence of a dispersive and absorbing semiconductor quantum dot. By using macroscopic approach and Green's function method, quantization of electromagnetic field is investigated. Interaction of a two-level atom , which is doped in a semiconductor quantum dot, with the quantized field is considered and its spontaneous emission ...

Synthesis and physicochemical properties of CuMn2O4 nanoparticles; a potential semiconductor for photoelectric devices

CuMn2O4 nanoparticles, a semiconducting materials with tunable functionalities in solid oxide fuel cell, was successfully synthesized via a sol-gel method using its respective metal cations sources i.e. Cu2+ and Mn2+ in an appropriate complexing agent.The vibrational frequencies below 1000 cm-1 of the obtained materials confirmed the formation of metal-oxygen (M-O:Cu-O, Mn-O) bond in the sample...
