The spectroscopic behavior of colloidal InP quantum dots (QDs) has been investigated as a
function of the mean QD diameter (which ranged from 26 to 60 Å). Absorption spectra show …

We have studied the spin dynamics in self-organized InAs/GaAs quantum dots by time-
resolved photoluminescence performed under strictly resonant excitation. At low …

The Fe-TiO2 photocatalysts synthesized by a sol–gel method have the mesoporous
structure with a narrow pore size distribution, large pore volume and high surface area. The …

Two types of lanthanide ion-doped titanium dioxide (Ln3+–TiO2) catalysts including La3+–
TiO2 and Nd3+–TiO2 were prepared by a sol–gel method. The effects of the lanthanide ion …

We report an in-situ fabrication of halide perovskite (CH 3 NH 3 PbX 3, CH 3 NH 3=
methylammonium, MA, X= Cl, Br, I) nanocrystals in polyvinylalcohol (PVA) nanofibers …

Quantization effects in semiconductor structures were first demonstrated in the early 1970s
in III-V quantum wells; these structures consisted of a thin epitaxial film of a smaller bandgap …

In an effort to elucidate the spin (rather than charge) degrees of freedom in colloidal
semiconductor nanocrystal quantum dots, we report on a series of static and time-resolved …

Experimental and theoretical studies of circular polarization of photoluminescence of
excitons (MCPL) in semiconductors placed in an external magnetic field are reviewed. The …

Due to the fact that transition metal and rare earth ion do** may significantly alter and
enhance the optical characteristics of II-VI semiconductor nanoparticles, these materials …

As one fundamental property of light, polarization has a huge impact in quantum optics and
optoelectronics through light–matter interactions. However, the bright and near-unity …
