Transport Transition

The luminescence quenching of a random, crystalline one-dimensional model porous medium doped with rare-earth elements, is analyzed by considering the transport, transition, and interaction of the fundamental energy carriers. The quenching in nano porous media is enhanced compared to a single crystal, due to multiple scattering, enhanced absorption, and low thermal conductivity. The coherent wave treatment is used to calculate the photon absorption, in order to allow for field interference and enhancement. The luminescent and thermal emission is considered as incoherent. The luminescence quenching and non-linear thermal emission, occurring with increasing irradiation intensity, are predicted.

Self Trapping

The electron–phonon (e–p) interaction in three-dimensional (3D), two-dimensional (2D) and one-dimensional (1D) ternary mixed crystals is studied. The e–p interaction Hamiltonians including the unit cell volume variation in ternary mixed crystals are obtained by using the modified random-element-isodisplacement model and Born–Huang method. The polaronic self-trapping energy and renormalized effective mass of GaAs[Formula: see text]Sb[Formula: see text], GaP[Formula: see text]As[Formula: see text] and GaP[Formula: see text]Sb[Formula: see text] compounds are numerically calculated. It is confirmed theoretically that the nonlinear variation of the self-trapping energy and effective mass with the composition is essential and the unit cell volume effects cannot be neglected except the weak e–p coupling. The dimensional effect cannot also be ignored.
