Colour tunability in a bimodal fluorescent hybrid nanostructure UCNPs@AuNPs@QDs

Singh, P.; Singh, P.; Prakash, R.; Rai, S.B.; Singh, S.K. (Elsevier B.V., 2020-10)

In the present work, lysine modified NaY0.78Er0.02Yb0.2F4 upconversion nanoparticles (UCNPs, positively charged) and lysine modified ZnSe:Mn2+ quantum dots (QDs, positively charged) are attached onto the surface of citrate ...
Development of inorganic-organic hybrid nanostructured material for H2O2 sensing application

Kumar, A.; Shahi, P.K.; Bahadur, A.; Singh, S.K.; Prakash, R.; Yadav, R.A.; Rai, S.B. (Institute of Physics Publishing, 2020-05)

An organic-inorganic hybrid nanoparticle (HNPs) composed of Sm(TTA)3Phen, a coordination compound, and NaY0.78Er0.02Yb0.20F4, an upconversion nanoparticles (UCNPs), has been developed and used for H2O2 sensing application. ...
Effect of Bi3+ ion on upconversion-based induced optical heating and temperature sensing characteristics in the Er3+/Yb3+ co-doped La2O3 nano-phosphor

Yadav, R.S.; Kumar, D.; Singh, A.K.; Rai, E.; Rai, S.B. (Royal Society of Chemistry, 2018)

The upconversion-based optical heating and temperature sensing characteristics are investigated in the Er3+/Yb3+/Bi3+ tri-doped La2O3 nano-phosphor synthesized through a solution combustion method. The structural measurements ...
Effect of host on the radiative (upconversion emission) as well as non-radiative relaxation (laser induced optical heating) in Tm3+/Yb3+ co-doped phosphors

Dwivedi, A.; Kumar, D.; Rai, S.B.; Rai, A.K. (Elsevier B.V., 2020-10)

Tm3+/Yb3+ co-doped YVO4 (YVO:Tm, Yb); GdVO4 (GVO:Tm, Yb); Y2O3 (YO:Tm, Yb); Gd2O3 (GdO:Tm, Yb) and CaAl2O4 (CAO:Tm, Yb) phosphor samples have been synthesized using high temperature Solid State Reaction method. X-ray ...
Effect of Synthesis Techniques on the Optical Properties of Ho 3+ /Yb 3+ Co-doped YVO 4 Phosphor: A Comparative Study

Dwivedi, A.; Rai, E.; Kumar, D.; Rai, S.B. (American Chemical Society, 2019-04-16)

The Ho 3+ /Yb 3+ -codoped YVO 4 phosphors have been synthesized by three different techniques (viz., solution combustion, sol-gel, and solid-state reaction techniques). X-ray diffraction patterns confirm the formation of ...
Enhanced multimodal behaviour of Tm3+/Yb3+ co-doped YTaO4 ceramic material through Bi3+ activation and sensitization: Application as a spectral converter

Roy, A.; Dwivedi, A.; Kumar, D.; Mishra, H.; Rai, S.B. (Elsevier Ltd, 2020-11)

The multimodal [Upconversion (UC), Downshifting (DS) and Quantum cutting (QC)] behaviour of Tm3+/Yb3+ co-doped YTaO4 ceramic material is investigated extensively. The samples are prepared by solid-state reaction method at ...
Impact of viscosity on photo-induced bimodal emission, decay profile and energy transfer in lanthanide based hybrid nanostructure

Shahi, P.K.; Prakash, R.; Rai, S.B. (Elsevier B.V., 2020-09)

The effect of viscous media on fluorescence intensity and lifetime of hybrid nanoparticles (HNPs) have been investigated in order to design viscosity sensor. HNPs are developed by using of Eu(TTA)3Phen (ETP) coordination ...
