Enhanced luminescence by tunable coupling of Eu3+ and Tb3+ in ZnAl2O4:Eu3+:Tb3+ phosphor synthesized by solution combustion method

Verma, Naveen; Marí, B.; Singh, Krishan Chander; Jindal, Jitender; Yadav, Suprabha; Mittal, Anuj (Springer-Verlag, 2019)

[EN] ZnAl2O4:Eu3+ or Tb3+ (1 mol%) and ZnAl2O4:Eu3+/Tb3+ with varied concentrations of Eu3+ and Tb3+ were prepared by solution combustion method. The photoluminescence spectra of synthesized compounds shows that simultaneous ...
Growth mechanism and morphology of ZnO/Eosin-Y hybrid films

Marí Soucase, Bernabé; Singh, Krishan Chander; Mollar García, Miguel Alfonso; Moya Forero, Mónica Mercedes; Rana, Ravi (Kexue Chubanshe, 2012)

Thin hybrid films of ZnO/eosin-Y were prepared by electrodeposition at -0.8 and -0.9 V in aqueous and non-aqueous baths at temperatures ranging from 40 to 90 °C with dye concentrations of 100 and 400 µmol·L-1 . The films ...
Optical properties of Yb3+ doped ZnO/MgO nanocomposites

Marí, B.; Singh, Krishan Chander; Verma, Naveen; Jindal, J. (Elsevier, 2016-08-15)

[EN] Yb3þ doped ZnO/MgO nanocomposite were prepared by combustion synthesis method. The samples were further heated to 1000 °C to improve their crystallinity and photoluminescent efficiency. The concentrations of Yb3þ ...
Red emitting MTiO3 (M = Ca or Sr) phosphors doped with Eu3+ or Pr3+ with some some cations as co-dopants

Marí Soucase, Bernabé; Singh, Krishan Chander; Cembrero Coca, Paula; Singh, I.; Singh, D.; Chand, S. (Elsevier, 2013-10)

[EN] Ca (or Sr)TiO3:Eu3+ , M (Li + or Na+ or K+ ) and CaTiO3:Pr 3+ , M (Li + or Na+ or Ag+ or K+ or Gd3+ or La3+ ) powders were prepared by combustion synthesis method and the samples were further heated to !1000 ...
Remarkable influence of heat treatment on AC irreversibility line and flux pinning properties in (Y1-xEux)SrBaCu3O6+z

Morghi, Redwane; Nafidi, Abdelhakim; Aboulkassim, Abdeljabar; Khallouq, Kaltoum; Chaib, Hassan; Khalal, Ali; Tirbiyine, Ahmed; Taoufik, Ahmed; Marí, B.; Mollar Garcia, Miguel Alfonso; Singh, Krishan Chander (INOE Publishing House, 2013-11)

Polycrystalline samples (Y1-xEux)SrBaCu3O6+z have been synthesized by solid state reaction method with two distinguished heat treatment. The irreversibility line and flux pinning proprieties (pinning force density) has ...
Structural and optical properties of Ta2O5:Eu3+: Mg2+ or Ca2+ phosphor prepared by molten salt method

Verma, Naveen; Marí, B.; Singh, Krishan Chander; Jindal, Jitender; Mollar García, Miguel Alfonso; Rana, Ravi; Pereira, A.L.J.; Manjón Herrera, Francisco Javier (AIP Publishing, 2016)

. Ta2O5:Eu3+: Mg2+ or Ca2+ phosphor materials were prepared by molten salt method using KCl as flux. The Xray diffraction (XRD) patterns illustrated that the well crystallized Ta2O5:Eu3+: Mg2+ or Ca2+ were formed in the ...
Synthesis and enhanced luminescent characterization of SrAl4O7:Eu2+,RE3+ (RE= Nd, Dy) nanophosphors for light emitting applications

Singh, D.; Tanwar, V.; Samantilleke, Anura; Marí, B.; Singh Kadyan, P.; Singh, Krishan Chander (Springer Verlag (Germany), 2016-11)

[EN] SrAl4O7:Eu2+,RE3+ (RE = Nd, Dy) nanophosphors were efficiently synthesized with a facile fast gel com- bustion procedure in presence of air. During the synthesis process, urea was used as an organic fuel. Boric acid ...
