A series of Europium (III) and Terbium (III) co-doped GdSrAl 3 O 7 color-tunable nanophosphors were synthesized by a simplistic, streamlined and self-propagating, urea- assisted solution combustion synthesis process. The structural and luminescence characteristics of synthesized Eu 3+ /Tb 3+ co-doped Gadolinium Strontium Aluminate nanocrystalline phosphors were validated using powder X- ray diffraction (PXRD), scanning 2 electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X- ray analysis (EDAX), and photoluminescence spectra studies. The morphological studies revealed that the synthesized co-doped phosphor crystals seemed to be agglomerated spherical- shaped porous nanocrystalline particles with interconnected boundaries. Through diffuse reflectance (DR) spectroscopy, the optical band gap values for nanocrystalline phosphors were also studied. The simultaneous presence of these two rare earth ions may provide specific luminous assets, including efficient energy transfer along with controlled emissions. The detailed analysis of the photoluminescence excitation (PLE) and photoluminescence emission (PL) spectra of Europium (III) and Terbium (III) co-doped GdSrAl 3 O 7 revealed that Tb 3+ effectually sensitized Eu 3+ ion and that the energy transfer could be precisely controlled to achieve color- tunable emission by varying the proportions of doped ions. The non- radiant energy loss i.e. concentration quenching phenomenon was also probed in detail. Additionally, by using their emission data, colorimetric traits including Commission International de I’Eclairage 1931 color coordinates, color purity (CP), and correlated color temperature (CCT) were also obtained. The photometric properties of developed nanocrystalline co-doped phosphor materials introduce new prospects and layout potentials for upgraded luminous materials that can be used in field emission displays, solid- state technologies, multicolor display applications and a variety of illumination strategies.

Keywords: solution combustion, nanocrystalline, phosphors, photoluminescence, color coordinates.
