Effects of Ce3+ concentration, beam voltage and current on the cathodoluminescence intensity of SiO2:Pr3+–Ce3+ nanophosphor

Upconversion Luminescence and Photodegradation Performances of Pr Doped Y2SiO5 Nanomaterials

“…So far, three kinds of methods are commonly used to synthesize upconversion nanomaterials, including thermal decomposition [17][18][19], hydrothermal synthesis [20,21], and ionic liquids-based synthesis [22]. In addition, sol-gel method has potential for synthesizing high quality upconversion nanomaterials of high luminescence efficiency and usually used as the first choice to doping ions since it provides a way of mixing in molecular level of the reactants [23,24], which has also been used in this study.…”

Luminescence Dependence of Pr3+ Activated SiO2 Nanophosphor on Pr3+ Concentration, Temperature, and ZnO Incorporation

“…Studies of energy transfer process between Pr 3+ and other ions codoped on the same host matrix have been reported. For example, Tripathi et al 15 and Mhlongo et al 17 studied the energy transfer between Pr 3+ -Eu 3+ and Pr 3+ -Ce 3+ ion pairs, respectively, whereas Nie et al 16 reported efficient energy transfer between Pr 3+ and Cr 3+ . Interest has also been focused on semiconductor The Journal of Physical Chemistry C ARTICLE nanocrystals, "quantum dots", because they are considered to be another good choice as sensitizing centers for radiative relaxation of activator ions because their excitation cross sections are very high as a result of the efficient band-to-band absorptions.…”

Combustion synthesis of CaSc2O4:Ce3+ nano-phosphors in a closed system

“…Recently, rare-earth ions doped oxide nanophosphors have attracted much attention in the field of fluoroimmunoassay [1,2], cell detection [3], and solar cell [4] due to their stable physical and chemical properties [5] as compared to that of fluorides [6] and sulfides [7]. Highly fluorescent nano-phosphors with low particle size, even size distribution and good dispersity are needed to meet the requirements.…”
