Crystal Phase Refinement and Optical Features of Highly Efficient Green Light Radiating CaY(VO): Er Nanophosphors for Emerging Solid-state Lighting Applications.

CaY(VO) phosphor activated with Er ions have been developed by the urea-aided solution combustion technique. XRD profiles assisted with Rietveld refinement executed over-developed Er-activated CaY(VO) powder, revealed a trigonal phase with the R3c space group. The electron microscope techniques namely TEM and SEM characterize the size and surface-linked qualities of the developed nanopowder, respectively.

Crystal Chemistry and Photoluminescent Aspects of Bright Orange Light Emitting Sm- Activated BaBiVO Nanomaterials for Advanced Illuminating Applications.

In the present system, Sm activated BaBiVO nanomaterial series radiating orange-red light was developed via an efficient approach of solution combustion method. The structural examinations using XRD analysis indicate that the sample is crystallized into the monoclinic phase with the P21/a (14) space group. The elemental composition and morphological conduct were studied via energy dispersive spectroscopy (EDS) and scanning electron microscopy (SEM) respectively.

Combustion Synthesis and Study of Double Charge Transfer in Highly Efficient Cool White-emitting Dy Activated Vanadate-based Nanophosphor for Advanced Solid-state Lighting.

A series of CaGd(VO): Dy (x = 0.01-0.20) nanophosphor crystals emitting a cool white light were synthesized by solution combustion methodology.

Screening of biologically important Zn by a chemosensor with fluorescent turn on-off mechanism.

Reported herein the synthesis, characterization and biologically important zinc ion binding propensity of a weakly fluorescent chemosensor, 4-methyl-2,6-bis((E)-(2-(4-phenylthiazol-2-yl)hydrazono)methyl)phenol (1). H NMR spectroscopic titration experiment reveals the binding knack of 1 to the essential Zn. The photo-physical studies of 1 exhibit an enhancement in the fluorescence by several folds upon binding with the zinc ions attributed to PET-off process, with a binding constant value of 5.

Appraisal of salinity and fluoride in a semi-arid region of India using statistical and multivariate techniques.

Various physico-chemical parameters, including fluoride (F(-)), were analyzed to understand the hydro-geochemistry of an aquifer in a semi-arid region of India. Furthermore, the quality of the shallow and deep aquifer (using tube well and hand pumps) was also investigated for their best ecological use including drinking, domestic, agricultural and other activities. Different multivariate techniques were applied to understand the groundwater chemistry of the aquifer.
