Undoped and europium doped CaMoO4 SrMoO4 scheelites are synthesized using a complex polymerization method. The phase purity of the sample is confirmed powder X-ray diffraction (PXRD). photoelectron spectroscopy (XPS) was carried out to confirm oxidation states various constituents dopant elements also presence oxygen vacancies. Interestingly both on irradiation with UV light give blue green emission respectively. On doping, it found that molybdate Eu(3+) ion energy transfer more efficient in...
Visible host emission and dynamics of host–dopant energy transfer in LaPO<sub>4</sub>:Eu phosphor is investigated using PL complimented by DFT.
Blue-white light emitting Sr2CeO4 and red Sr2CeO4:Eu3+ nanoparticles were prepared using a polymeric precursor route. The synthetic conditions optimized to achieve suitable calcination temperature heat treatment time. systems characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) differential thermal (DTA). concentration of dopant ions was maximise the PL intensity. effect on excitation, emission lifetime spectroscopy investigated in...
Recent decades have experienced the discovery of numerous complex materials. At root complexity underlying many these materials lies a large number contending atomic- and largerscale configurations. In order to obtain more detailed understanding such systems, we need tools that enable detection pertinent structures on all spatial temporal scales. Towards this end, suggest new method applies both static dynamic systems which invokes ideas from network analysis information theory. Our approach...
Poly(ethylene oxide), PEO, based solid polymer electrolyte with different loadings of a lithium salt, bis(trifluoromethanesulfonyl)imide (LiTFSI), has been investigated to study the role PEO–Li cross-linking on segmental dynamics and free volume structure PEO which consequently determine thermal, mechanical, ion conduction properties electrolyte. In order investigate interrelation between dynamics, structure, mechanism, broadband dielectric spectroscopy positron annihilation have employed....

Tetraphenylethane-1,2-diylbis(phosphoramidate) in conjugation with a room temperature ionic liquid chloroform medium is reported for the first time liquid-liquid extraction of thorium (Th). The extracted Th(IV) collected as white solid organic medium, thereby facilitating its easy separation. A high distribution ratio (D) (12.4 ± 0.1) × 103 2-8 mol L-1 acidity range and decontamination factors (α) from uranium, lanthanides, number transition elements makes this process versatile selective....
