Effect of Cr3+ doping on structural and optical properties of Eu3+ doped LaVO4 phosphor

Rai, Ekta; Yadav, Ram Sagar; Kumar, Dinesh; Singh, Akhilesh Kumar; Fulari, Vijay Janardhan; Rai, Shyam Bahadur (Royal Society of Chemistry, 2023-01-31)

In this work, the Eu3+, Cr3+ doped and co-doped LaVO4 phosphors have been prepared through a high temperature solid-state reaction method. The powder XRD patterns of phosphors are very sharp and intense, which reflects a ...
Erratum: Effect of a chelating agent at different pH on the spectroscopic and structural properties of microwave derived hydroxyapatite nanoparticles: a bone mimetic material

Mishra, Vijay Kumar; Bhattacharjee, Birendra Nath; Kumar, Devendra; Rai, Shyam Bahadur; Parkash, Om (Royal Society of Chemistry, 2022-03-04)

In the present investigation, the effect of a capping agent (EDTA) and pH on the optical and structural characteristics of HAp nanoparticles (NPs) has been studied. Six samples of HAp were synthesized under six different ...
Silver nanoparticles embedded hybrid organometallic complexes

Shahi, Praveen Kumar; Prakash, Rajiv; Rai, Shyam Bahadur (American Institute of Physics Inc., 2018-06-27)

A novel hybrid material comprising of two β-diketonate complexes, Tb(ASA)3Phen (TAP) and Eu(TTA)3Phen (ETP), has been synthesized and studied its photo-physics, energy transfer and optical thermometry applications. Using ...
Structure of Apatite Nanoparticles Derived from Marine Animal (Crab) Shells

Bhattacharjee, Birendra Nath; Mishra, Vijay Kumar; Rai, Shyam Bahadur; Parkash, Om; Kumar, Devendra (American Chemical Society, 2019-07-26)

In the present investigation, crab shells as seafood wastes were successfully recycled into an extremely useful biomaterial by the thermal treatment method. Thermogravimetric-differential thermal analysis studies concluded ...
