Multifunctional Er3+–Yb3+ codoped Gd2O3 nanocrystalline phosphor synthesized through optimized combustion route

Up and down conversion fluorescence studies on combustion synthesized Yb3+/Yb2+: MO-Al2O3 (M=Ca, Sr and Ba) phosphors

“…The phosphor samples have been prepared through combustion method using urea as an organic fuel as described earlier [21]. The following composition of the phosphor has been selected for study:…”

Blue upconversion luminescence of CaMoO4:Li+/Yb3+/Tm3+ phosphors prepared by complex citrate method

“…Currently, these materials can be used for medical diagnostics and nano-biotechnology such as bio labeling, bioimaging [8,9]. However, they have the important problems of rigorous low efficiency, which stringently limit their pervading application [10,11]. Consequently, it will be of great interest to significantly increase the UC emission intensity in order to deploy their potential applications.…”

Synthesis and luminescent properties of Dy3+:GAG nanophosphors

“…Rare earth (RE) ions activated phosphors, have found to be excellent luminescent materials because of their marked improvements in lumen output, color rendering index, energy efficiency and greater radiation stability [6][7][8][9]. In recent years, interest in the rare earth doped nanocrystalline host has increased due to their unique optical behavior [10]. Luminescent nanophosphors are also attractive in the field of nanobiotechnology as they have dimensions (diameters) in good match with those of biological structures, such as DNA, proteins, and antibodies.…”

“…Luminescent nanophosphors are also attractive in the field of nanobiotechnology as they have dimensions (diameters) in good match with those of biological structures, such as DNA, proteins, and antibodies. They can be used for analytical, diagnostic, and therapeutic purposes [10][11][12]. The RE ions are characterized by a partially filled 4f shell that is shielded by 5s 2 and 5p 6 electrons.…”
