The development of a pixel-structured scintillator has recently been exploited to confine optical transport onto a corresponding photodiode pixel. This conceptual design of scintillators may provide high detection efficiency while preserving high spatial resolution in digital X-ray imaging detector systems. The sedimentation approach is one method to fill gadolinium-oxysulfide phosphors into a ...

Lacking an effective strategy to simultaneously address the challenges of quantum efficiency, luminescence intensity and thermal stability has become key bottleneck for further development large-scale application solid-state lighting technology. Herein, inspired by defect-engineering used in photoelectrocatalytic photovoltaic materials, we acted a diametrically opposite way unprecedentedly prop...

Ba9Sc2Si6O24:Eu2+ phosphors have been reported to acquire several desired properties such as emission and excitation spectra, thermal stability, etc. needed for phosphor converted LED. Solid state reaction has invariably used prepare these phosphors. Synthesis at temperatures high 1450 °C was required in all previous studies. It is shown that use of flux can bring down the synthesis temperature...

The performance of colloidal CuInS2/CdS nanocrystals as phosphors for full-spectrum luminescent solar concentrators has been examined. Their combination of large solar absorption, high photoluminescence quantum yields, and only moderate reabsorption produces the highest projected flux gains of any nanocrystal luminophore to date.

Chromium doped luminescent phosphors display numerous spectral features that can be useful for designing modern multi-functional materials.

PURPOSE Contrast, sharpness, enhancement, and density can be changed in digital systems. The important question is to what extent the changes in these variables affect the accuracy of caries detection. MATERIALS AND METHODS Forty eight extracted human posterior teeth with healthy or proximal caries surfaces were imaged using a photostimulable phosphor (PSP) sensor. All original images were pr...

This paper addresses the potential for predicting heat flux from thermographic phosphor measurements. Temperature can be measured using thermographic phosphors by extracting the intensity decay of the phosphor, which is temperature dependent. This measured temperature can then be used to estimate boundary heat fluxes, which is often called the inverse heat conduction problem. Heating rate can a...

This study evaluated the technique errors of full mouth series exposed with two intraoral radiography receptor systems; traditional film-based and PSP-based (photostimulable phosphor) receptors. Full mouth series (n=405) were randomly selected: three series per each student for film-based (n=81) and PSP-based (n=102). All images (1514 film and 1754 PSP images) were evaluated in four categories ...

Surface coverings using nanomaterials of silica nanoparticles and poly (methyl methacrylate) – abbreviated “PMMA-silica nanomaterials” are introduced to the Y 2 O S:Eu 3+ phosphor through four distinct approaches. The objective is enhance phosphorescence prolonged sustainability. Using immerse-daubing along with sol-gel approach (Stober way), it possible have phosphors covered relatively-monodi...
