Investigation of a new way of synthesis for Nano crystallites of La2O2S & 1%Ln3+ (Ln = Pr, Eu, Tb, Dy, Er) doped La2O2S and study their structural and optical properties
(Journal of Alloys and Compounds, 2021)
Nano-crystallite Lanthanum oxysulfide (La2O2S), a versatile compound with a wide range of applications, has been synthesized by the Solid State, Hydrothermal, and a novel Furnace Combustion technique. The last one limits ...
Search for high temperature memory effects in magnetic nanoparticles
(Journal of Alloys and Compounds, 2021)
Nanoparticle materials have become a promising candidate for a new kind of storage media based on thermally induced memory effects due to the possibility to tailor their magnetic properties and behaviour. In this study, ...
Highly sensitive multiparametric luminescent thermometer for biologically-relevant temperatures based on Mn4+, Ln3+ co-doped SrTiO3 nanocrystals
(Journal of Alloys and Compounds, 2021)
The constant striving to improve the quality of thermal imaging with the use of luminescent thermometers imposes the search for new materials with better and better thermometric properties. The facility in the modulation ...
Weak ferromagnetism and exchange bias effect in Co1+yAl2-yO4/SiO2 nanocomposites
(Journal of Alloys and Compounds, 2021)
Nanocomposites made of magnetic spinel oxide Co1+yAl2-yO4 nanoparticles (NPs) with y = 0.93, 1.20 and 1.34 dispersed in an amorphous SiO2 matrix were prepared by a sol-gel method. The average crystallite size DXRD of about ...
Effect of citric acid on the morpho-structural and magnetic properties of ultrasmall iron oxide nanoparticles
(Journal of Alloys and Compounds, 2021)
The structural and magnetic properties of iron oxide nanoparticles obtained by the precipitation of iron ions in the presence of different amounts of citric acid were studied. The citric acid acts as a capping agent and ...
