Effect of fuels on structure, morphology, and spectroscopy of combustion-synthesized Y2O3:Eu3+ nanoparticles: Towards applications in optoelectronic devices and biomedicine

Eu3+ ion doped yttria nanoparticles (Y2O3:Eu3+ NPs) were synthesized by a combustion method using urea (U), glycine (G), and ethylenediaminetetracetic acid (E) as fuels. Combustion parameters including adiabatic flame temperature and emitted heat, were calculated and found to increase with the fuel...

Description
Summary:Eu3+ ion doped yttria nanoparticles (Y2O3:Eu3+ NPs) were synthesized by a combustion method using urea (U), glycine (G), and ethylenediaminetetracetic acid (E) as fuels. Combustion parameters including adiabatic flame temperature and emitted heat, were calculated and found to increase with the fuel molecular weight. XRD pattern confirmed a body-centered cubic (BCC) phase with the Ia3 space group where Eu³⁺ ions occupied both C2 and S6 sites. Y2O3:Eu3+ NPs prepared with higher molecular weight fuels, exhibited the superior photoluminescence (PL) of the orange-red (O-R) bands. PL spectra revealed the dominant 5D0 - 7F2 transitions were driven by the energy transfer process from S6 sites to C2 sites via electric multipolar interactions. Chromaticity parameters confirmed the potential of these Y2O3:Eu3+ NPs for optoelectronic applications, with the strong luminescence in the O-R region, making them suitable for biomedical fluorescence imaging.
