Temperature dependence of continuum and time resolved photoluminescence of germanium nanostructures
Authors
Abstract:
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 time and temperature dependence of the luminescence for different bands were investigated, which confirmed our idea about the origin of the luminescence.

Temperature dependence of time-resolved photoluminescence in closely packed alignment of Si nanodisks with SiC barriers
We study the temperature dependence of time-resolved photoluminescence (PL) in closely packed alignment of Si nanodisks (NDs) with SiC barriers, fabricated by neutral beam etching using bio-nano-templates. The PL time profile indicates three decaying components with different decay times. The PL intensities in the two slower decaying components depend strongly on temperature. These temperature ...

A combination of wavelength-, time-, and polarizationresolved photoluminescence imaging on isolated P3HT nanofibers of varying molecular weight (from 10 to 65 kDa) has revealed a transition in dominant exciton coupling from primarily interchain (H-aggregation) for low molecular weight nanofibers, to predominantly intrachain (Jaggregation) coupling for high molecular weight nanofibers. Based on ...

Cupper Oxide structures with a variety of novel morphologies are synthesized using cupper foil as substrate via a solution route. The structure, morphology and phase of the as-synthesized nanostructures are analyzed by various techniques. SEM images show gradual development of hierarchical structures of copper oxide with different morphology. In order to study the effect of reaction time and te...

Low Temperature Photoluminescence in Ultra-Thin Germanium Quantum Wells
We measured the photoluminescence (PL) spectra of a series of Gen quantum wells as a function of temperature, from 2K to 50K. The PL spectra at 2.1K are dominated by broad emission lines, which can be interpreted as recombination across the indirect gap of the Si/Ge microstructure and are strongly in uenced by the interface morphology of each sample. Beyond T & 15K, all samples show identical s...
