چکیده
In this study, we report the optical properties and carrier dynamics of different surface dimensionality n-type wurtzite InN with various concentrations using photoluminescence (PL) an energy-dependent, time-resolved (ED-TRPL) analysis. Experimental results indicated that morphology can be controlled by growth temperature, from one-dimensional (1D) nanorods to two-dimensional (2D) films. Moreover, donor-like nitrogen vacancy (VN) is responsible for increase in concentration due lowest formation energies samples. The PL also reveal emission peaks are higher samples 2D features than 1D features. These anomalous transitions explained as recombination Mahan excitons localized holes, further proved a theoretical model, activation energy photon energy-dependent lifetime

Temperature dependence of continuum and time resolved photoluminescence of germanium nanostructures
Germanium nanostructures were generated in the post annealed germanium oxide thin films. Visible and near infrared photoluminescence bands were observed in the samples annealed at 350°C and 400°C, respectively. These different luminescence ranges are attributed to the presence of the defects in oxide matrix and quantum confinement effect in the germanium nanostructures, respectively. Decay ti...
متن کاملProbing Nucleation Mechanism of Self-Catalyzed InN Nanostructures
The nucleation and evolution of InN nanowires in a self-catalyzed growth process have been investigated to probe the microscopic growth mechanism of the self-catalysis and a model is proposed for high pressure growth window at ~760 Torr. In the initial stage of the growth, amorphous InNx microparticles of cone shape in liquid phase form with assistance of an InNx wetting layer on the substrate....
متن کاملTime-resolved photoluminescence measurement on polythiophene derivative
We measured the time-resolved photoluminescence (PL) on a film of a polythiophene derivative to investigate the formation and relaxation processes of a self-trapped exciton (STE). On the highand low-energy sides of the PL spectrum, we observed an ultrafast decay component emitted during the STE formation. We also found that PL of the derivative originates from two STE states with opposite symme...

متن کاملTime-resolved study of photoluminescence polarization in a-C:H ®lms
The decays of intensity and polarization anisotropy of the photoluminescence (PL) of polymer-like amorphous carbon ®lms have been measured at 300 and 80 K using 4.13 and 2.15 eV excitation. For emission energies, Eem, between 1.8 and 3.5 eV, PL polarization anisotropy decreases within 100 ps and reaches a plateau within 1 ns. The anisotropy plateau increases from 0.02 to 0.12 and the intensity ...
