Pushpal Ghosh Assistant Professor, Department of Chemistry, Dr. Finally, photonic applications of RE-doped nanofluorides for energy efficient lighting, improved solar cells and biophotonic applications like photodynamic therapy, and biological detection techniques including in vivo and in vitro bioimaging are presented. Prassana Parab Prosenjit Singa Deo Puja Sharma Pushpal Goswami R K Pai R. The role of surface modification and functionalization for improving the luminescence intensity, stability, aqueous dispersity/dispersibility and biocompatibility of the materials is discussed. In the following, different synthesis strategies which have been developed for tuning the crystal phase, shape, size, and morphology of the host nanomaterial are presented. In addition, the effect of surface plasmon resonance (SPR) on the rare earth luminescence is discussed. Rahul Kumar Sharma, Pushpal Ghosh, Ashwani Kumar and Mohammed Latif Khan Activation of Electrophile/Nucleophile Pair by a Nucleophilic and Electrophilic. prepared by modifying the previously reported methods (Ghosh and Mudring. Pushpal Ghosh,a Suparna Sadhu a and Amitava Patra a Author affiliations Abstract The solemulsiongel method is used for the preparation of about 57 nm size Eu 2 O 3 doped and coated Y 2 SiO 5 nanoparticles at 1300 ☌. Then, the influence of particle size and surface, shape and lattice strain, as well as the crystal phase of the host materials on the optical properties of rare earth based nanomaterials are illustrated. Jitendra Kumar Singh,1, Rahul Kumar Sharma,2, Pushpal Ghosh,2 Ashwani Kumar. First, the underlying photoluminescence mechanisms like up- and downconversion (UC and DC), charge transfer (CT) and energy transfer (ET) between optically active trivalent RE ions are explained. Ghosh, Pushpal Patra, Amitava (2016): Influence of Crystal Phase and Excitation Wavelength on Luminescence Properties of Eu3+-Doped Sodium Yttrium Fluoride. This review article aims providing and introduction to the field and giving a critical overview about the latest developments in this fast evolving field. Pushpal Ghosh and Amitava Patra doped nanocrystals can be good replacement of organic dyes in two-photon confocal microscope imaging. It reveals that the core-shell structure shows better upconversion emission efficiency.Rare-earth (RE) doped binary and ternary fluoride nanomaterials are currently receiving the highest attention as phosphor materials due to their potential for a wide range of photonic and biophotonic applications. The effective decay time calculated are 230 and 110 μ s for core-shell and doped nanorods, respectively, indicating the removal of surface defects due to surface coating.

Bright blue (475 nm) and red (650 nm) upconversion emissions associated to G 1 4 → H 3 6 and F 3 2 → H 3 6 transitions were observed and a significant higher in upconversion emission intensity is observed in core-shell nanorods. A simple, robust and scalable route to prepare sub-50 nm soft PDMS nanoparticles for intracellular delivery of anticancer drugs. Eu-Doped BaF 2 Nanoparticles for Bioimaging Applications. Analysis suggests that the lattice strain plays an important role on the upconversion emission.

Tensile strain is observed for LaPO 4 : Yb – Tm doped material but compressive strain is obtained for LaPO 4 : Yb / Tm core-shell material. Ivanov Sandeep Nigam Archna Pandey Pushpal Ghosh Show more detail. Parul Ghosh (née Biswas 191513 August 1977) was an Indian playback singer. The synthesized derivatives were evaluated for in vitro anticancer activity against B16F10 and MCF-7 cell lines for the first time and showed promising anticancer activity. The morphologies, structure, formation mechanism, and upconversion emission properties of these nanocrystals are investigated in detail. An efficient synthesis of 3-(3-oxoaryl) indole derivatives over existing methodology by using green chemistry approach was developed. A solution based hydrothermal method is used for the preparation of LaPO 4 : Yb – Tm doped and LaPO 4 : Yb / Tm core-shell upconverted nanorods.
