Green and Continuous Hydrothermal Synthesis of Nanophosphors for Biomedical Applications

Gruar R., Kellici S., Tighe C., Darr J., UCL, UK

The luminescent properties of Y2O3:Eu have attracted considerable research interest due to the emission and chemical stability of the oxide phosphor. Subsequently, we evaluated the calcination of YOOH:Eu (4% dopant) synthesised directly in a continuous [...]

Enhanced Photoluminescence Properties of Li/Al-doped YPO4:Eu phosphors

Yi S.S., Silla University, KR

we have prepared different concentrations of Li/Al-doped YPO4:Eu0.05 phosphors by solid state reaction method and the synthesized materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), excitation and emission measurements. The dependence of [...]

Control of solid surface properties by electron beam processing

Vasiljeva I.V., Mjakin S.V., Engineering Technology Center RADIANT, Ltd., RU

The effect of electron beam treatment upon various materials (oxides, sulfides, ceramics, polymers) is studied to clarify the general features of chemical reactions involving surface functional groups in correlation with the process parameters. The mechanisms [...]

Laser pyrolysis – a platform technology to produce functional nanoscale materials for a range of applications

Chiruvolu S., Li W., Ng M., Du K., Ting N.K., McGovern W.E., Kambe N., Mosso R., Drain K., NanoGram Corporation, US

Nanoscale materials continue to generate ever increasing levels of interest for applications in a broad-range of fields. Concurrently variety of synthesis methods are being explored and developed for the synthesis and production of nanoparticles including [...]
