Ultraviolet photoluminescence of ZnO quantum dots sputtered at room-temperature.
We observe ultraviolet photoluminescence from sputtered ZnO quantum dots which are fabricated with no annealing steps. The nanocrystals are embedded in amorphous SiO2 and exhibit a narrow size distribution of 3.5 ± 0.6 nm. Photoluminescence and transmittance measurements show a shift of ultraviolet emission and absorption of the dots compared to bulk ZnO material. This work paves the way for ch...
متن کاملTemperature dependent photoluminescence in oxygen ion implanted and rapid thermally annealed ZnO/ZnMgO multiple quantum wells
The authors investigate the effect of oxygen implantation and rapid thermal annealing in ZnO/ZnMgO multiple quantum wells using photoluminescence. A blueshift in the photoluminescence is observed in the implanted samples. For a low implantation dose, a significant increase of activation energy and a slight increase of the photoluminescence efficiency are observed. This is attributed to the supp...
متن کاملCarrier-density dependence of the photoluminescence lifetimes in ZnCdSe/ZnSSe quantum wells at room temperature
Photoluminescence lifetimes have been measured at room temperature as a function of carrier density in ZnCdSe/ZnSSe quantum wells. We show that, at low carrier density (5310 – 5 310 cm), nonradiative recombination dominates, while radiative recombination becomes more dominant as the carrier density is increased from 5310 to 5310 cm. Above ;5 310 cm, band filling effects are shown to produce a s...
متن کاملInvestigation of temperature-dependent photoluminescence in multi-quantum wells
Photoluminescence (PL) is a nondestructive and powerful method to investigate carrier recombination and transport characteristics in semiconductor materials. In this study, the temperature dependences of photoluminescence of GaAs-AlxGa1-xAs multi-quantum wells samples with and without p-n junction were measured under both resonant and non-resonant excitation modes. An obvious increase of photol...
متن کاملLow 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...
