“…The author reported preliminary results from in situ XRF and ex situ XRD to further an understanding of the growth mechanism of the thin alloy film. A prolific author in this area, Dakhel 299 published information on conduction mechanisms in crystalline oxidised La and La-Mn films grown on p-type Si substrates using both XRF and XRD derived data. The author demonstrated that the addition of Mn oxide to La oxide, that almost terminated the hygroscopic products, neither changed the DC-conduction nature of the film, nor improved the insulating quality of pure La 2 O 3 .…”

This annual review of X-ray fluorescence covers developments over the period 2007-2008 in instrumentation and detectors, matrix correction and spectrum analysis procedures, X-ray optics and micro-fluorescence, synchrotron XRF, TXRF, portable XRF and on-line applications as assessed from the published literature. The trend set in previous years continues with an increase in the number of papers published on applications for XRF, including sample preparation, geological, environmental, archaeological, forensic, biological, clinical, thin films, chemical state and speciation studies. Earlier literature has not been ignored in that some of Archimedes oldest writing, previously hidden from sight in a medieval prayer book has now been revealed thanks to the power of modern m-SRXRF. X-ray optics now benefit from the use of poly-capillaries systems, equipment portability has been extended to include the TXRF configuration and readers will find several papers on the use of both two and three dimensional imaging to support environmental, geological and biological studies. The writing team would welcome feedback from readers of this review and invite you to complete the Atomic Spectrometry Updates questionnaire on www.asureviews.org. 9 Applications 9.1 Sample preparation 9.2 Geological and industrial minerals 9.3 Environmental 9.3.1 Aerosols and particulates 9.3.2 Consequences of industrial activity 9.3.3 Other environmental studies 9.4 Archaeological, cultural heritage and forensic 9.5 Industrial 9.6 Clinical and biological 9.7 Thin films and coatings 9.8 Chemical state and speciation 10 Abbrevations 11 References

Gold nanoparticles were grown in La-oxide thin films deposited on quartz and silicon substrates. These films were annealed in pure hydrogen gas atmosphere at 300°C for different durations 15 min, 30 min, and 45 min and characterised by the X-ray fluorescence (XRF) and X-ray diffraction. The matrix La-oxide remained amorphous up to 400°C. The fraction of Au in La-oxide host material was 7 % molar with crystallite size of 6.8 nm. The Au NPs slightly grew by annealing in H2 gas at 300 K. The samples were investigated by UV-Vis-NIR absorption spectroscopy and dc-electrical measurements. They exhibit conducting properties and with H2 gas annealing, they showed red shifting of the bandgap with remarkable reduction of optical absorption coefficient by ~25 % and remarkable increase in electrical conductivity ~124 %. A global study of the influence of low-temperature post annealing in H2 gas on the electrical, structural, optical, and optoelectronic properties was conducted
