They possess high colloidal stability, a saturation magnetization of up to 52 emu/g, and nearly spherical shape. The obtained clusters were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), energy-dispersive X-ray microanalysis (EDX), X-ray photoelectron spectroscopy (XPS) and magnetization measurements. New multi-core iron oxide magnetic nanoparticles doped with rare earth metals (Gd, Eu) were obtained by a one step synthesis procedure using a solvothermal method for potential biomedical applications.

Recent advances in various aspects of rare- earth (RE) doped borate based phosphors and their utilizations in SSL and light emitting diodes are summarized in this review article. The current research drive shows that phosphors based on the alkali-alkaline earth borates have transformed the science and technology due to their high transparency over a broad spectral range, their flexibility in structure and durability for mechanical and high-laser applications. Verma, Shefali Verma, Kartikey Kumar, Deepak Chaudhary, Babulal Som, Sudipta Sharma, Vishal Kumar, Vijay Swart, Hendrik C.Īs a novel class of inorganic phosphor, the alkali-alkaline earth borate phosphors have gained huge attention due to their charming applications in solid-state lighting (SSL) and display devices. Recent advances in rare earth doped alkali-alkaline earth borates for solid state lighting applications Kinetic parameters like trap depth and frequency factor were determined using Peak shape method from Chen's equation. All other important dosimetric characteristics like dose response and fading were carried out for the LSB:Ce (0.7 mol%) phosphor. In order to study the effect of dopant on the TL characteristics, LSB phosphor with different concentrations of Ce dopant was synthesized and the TL intensity was found to be maximum for a dopant concentration of 0.7 mol%. Among the different rare earth dopants, the phosphor doped with cerium was found to have a simple glow curve structure with a dosimetric peak at around 265Â☌ for a heating rate of 5Â☌/s. In this study polycrystalline powders of different rare earth doped thermoluminescent phosphors of Lithium Strontium borate (LSB) were synthesized by solid state sintering technique. Their sensitivity and thermal stability vary widely and depend strongly on the preparation method. Usually, the TL efficiency of pure borates is low and hence dopants have to be added to increase their TL output. Thermoluminescence (TL) of borates is remarkable in the field of radiation dosimetry because they can detect both neutron and gamma radiations.
