Structural changes and self-activated photoluminescence in reductively annealed Sr{sub 3}AlO{sub 4}F

Journal Article Green, Robert ; Avdeev, Maxim ; Vogt, Thomas ; ... - Journal of Solid State Chemistry

White light emission of self-activated photoluminescence (PL) in Sr{sub 3}AlO{sub 4}F under 254 nm light is only observed after annealing in a reducing atmosphere of 5%H{sub 2}/95%Ar. High-resolution neutron powder diffraction reveals that the FSr{sub 6} octahedrons and AlO{sub 4} tetrahedrons in this anti-perovskite structure are closer packed in reduced than in air-annealed samples which show no PL. Careful analysis of temperature-dependent neutron powder diffraction data establishes smaller isotropic displacement parameters for Sr(1) and O in Sr{sub 3}AlO{sub 4}F annealed in a reducing atmosphere indicating that the denser packing of the polyhedral sub-units leads to a slightly deeper potential formore »« less

Structures and self-activating photoluminescent properties of Sr{sub 3-x}A{sub x}GaO{sub 4}F (A=Ba, Ca) materials

Journal Article Green, Robert ; Vogt, Thomas - Journal of Solid State Chemistry

The synthesis, structures and photoluminescent properties of mixed oxyfluorides of the type Sr{sub 3-x}A{sub x}GaO{sub 4}F are compared to Sr{sub 3-x}A{sub x}AlO{sub 4}F (A=Ca, Ba) materials. In these compounds the F{sup -} and O{sup 2-} ions are ordered and located on two distinct crystallographic sites. When substituting Sr{sup 2+} by Ba{sup 2+} and Ca{sup 2+}, we find in Sr{sub 3-x}A{sub x}GaO{sub 4}F materials an ordering of the alkaline earth cations over the two crystallographic sites. The amount of Ba{sup 2+} ions that can be substituted into Sr{sub 3-x}A{sub x}GaO{sub 4}F is x{<=}1.2, which is slightly more than can be incorporatedmore »« less

Tunable photoluminescence of self-assembled GeSi quantum dots by B{sup +} implantation and rapid thermal annealing

Journal Article Chen, Yulu ; Wu, Shan ; Ma, Yinjie ; ... - Journal of Applied Physics

The layered GeSi quantum dots (QDs) are grown on (001) Si substrate by molecular beam epitaxy. The photoluminescence (PL) peak of the as-grown GeSi quantum dots has obvious blue shift and enhancement after processed by ion implantation and rapid thermal annealing. It is indicated that the blue shift is originated from the interdiffusion of Ge and Si at the interface between QDs and the surrounding matrix. The dependence of PL intensity on the excitation power shows that there are the nonradiative centers of shallow local energy levels from the point defects caused by the ion implantation, but not removed bymore »« less
