چکیده

We report on the photoluminescence properties of erbium Er doped InxGa1−xNa epilayers synthesized by metal organic chemical vapor deposition. The crystalline quality and surface morphology of Er doped In0.05Ga0.95N were nearly identical to those of Er doped GaN. The photoluminescence intensity of the 1.54 m emission in Er doped In0.05Ga0.95N was an order of magnitude lower than in Er doped GaN and decreased with the increase of the In content. The reduction in 1.54 m emission intensity was accompanied by enhanced emission intensities of deep level impurity transition lines. © 2009 American Institute of Physics. DOI: 10.1063/1.3193532

Erbium-doped AlN epilayers synthesized by metal-organic chemical vapor deposition

Erbium doped AlN epilayers (AlN:Er) have been grown by metal organic chemical vapor deposition. The 1.54 μm emission properties were probed by photoluminescence (PL) emission spectroscopy and compared with those of GaN:Er. Optimum intensity of the 1.54 μm emission from AlN:Er was obtained for growth temperature at 1050 °C. It was found that the emission intensity from AlN:Er is higher than that...

Photoluminescence of erbium doped microcrystalline silicon thin films produced by reactive magnetron sputtering

Microcrystalline silicon thin films doped with erbium were produced by RF sputtering and their structural, chemical and optical properties were studied by X-ray diffractometry at grazing incidence, Rutherford back scattering and optical transmission spectroscopy. The samples exhibit a sharp photoluminescence (PL) spectrum from the Er centres with the strongest peak positioned at 1.536 m with a...
