PROPERTIES
OF THE ACTIVE CENTERS IN PHOTONIC MATERIALS
♦
Theoretical
and experimental investigation of the quantum states and interactions
of the doping centers in the active photonic
materials in relation with
their distribution in the host lattice and with the structure of the
material
●
Variety, nature and structure of the
doping centers;
● Quantum
states and interactions
with the electromagnetic field (energy levels, selection rules,
transition probabilities and cross-sections, radiative properties);
● Characterization of the static
(crystal field) and
dynamic (electron-phonon) interactions of the doping ions with the host
material;
●
Homogeneous and inhomogeneous broadening of the spectral lines;
● Ion-ion
interactions and energy transfer processes;
● The
effects of the dimensionality and structure of the host material, and
the distribution of the doping centers on the static and
dynamic
spectroscopic properties.
