Physics and Mathematics of the Photoluminescence of Complex Systems
Ambra Lattanzi, Giuseppe Dattoli, Giuseppe Baldacchini
The photoluminescence (PL) of thermally evaporated Alq3 thin films has been studied in a few samples annealed and non-annealed and afterwards exposed to the laboratory atmosphere f…
Off-center impurity in alkali halides: reorientation, electric polarization and pairing to F center. IV. Reorientational rate
G. Baldacchini, R. M. Montereali, U. M. Grassano +5
This last Part IV is aimed at deriving relaxation rates (times) of an off-center Li+ impurity. We follow Christov's reaction rate method to define general rate equations in terms o…
Off-center impurity in alkali halides: reorientation, electric polarization and pairing to F center. III. Numerical calculations
G. Baldacchini, R. M. Montereali, U. M. Grassano +5
We carried out numerical calculations by an extended-Hueckel program in order to check the analytical results reported in the preceding Part I and Part II. We typically consider al…
Off-center impurity in alkali halides: reorientation, electric polarization and pairing to F center. II. In-plane rotation and polarizability
G. Baldacchini, R. M. Montereali, U. M. Grassano +5
Because of its inherent 2-D character, the eigenvalue equation for the hindered rotation around a normal cation site of an off-center impurity nearest-neighboring an F center is th…
Off-center impurity in alkali halides: reorientation, electric polarization and pairing to F center. I. Basic equations
G. Baldacchini, R. M. Monterealli, U. M. Grassano +5
Extending earlier work on a vibronic theory of the FA centers in alkali halides, the reorientation is now considered of an off-center Li+ impurity, either isolated or near an F cen…
