Distance Dependence of Gold-Enhanced Upconversion luminescence in Au/SiO2/Y2O3:Yb3+, Er3+ Nanoparticles
We report a localized surface plasmon enhanced upconversion luminescence in Au/SiO2/Y2O3:Yb3+,Er3+ nanoparticles when excited at 980 nm. By adjusting the silica spacer's thickness, a maximum 9.59-fold enhancement of the green emission was obtained. Effect of the spacer distance on the Au-Y2O3:Yb3+, Er3+ green upconversion mechanism was numerically simulated and experimentally demonstrated. In t...
متن کاملSynthesis of NaYF4:Yb3+, Er3+ upconversion nanoparticles in normal microemulsions
An interface-controlled reaction in normal microemulsions (water/ethanol/sodium oleate/oleic acid/n-hexane) was designed to prepare NaYF4:Yb3+, Er3+ upconversion nanoparticles. The phase diagram of the system was first studied to obtain the appropriate oil-in-water microemulsions. Transmission electron microscopy and X-ray powder diffractometer measurements revealed that the as-prepared nanopar...
متن کاملThe Upconversion Luminescence of Er3+/Yb3+/Nd3+ Triply-Doped β-NaYF4 Nanocrystals under 808-nm Excitation
In this paper, Nd3+-Yb3+-Er3+-doped β-NaYF₄ nanocrystals with different Nd3+ concentrations are synthesized, and the luminescence properties of the upconversion nanoparticles (UCNPs) have been studied under 808-nm excitation for sensitive biological applications. The upconversion luminescence spectra of NaYF₄ nanoparticles with different dopants under 808-nm excitation proves that the Nd3+ ion ...
متن کاملControlled Synthesis of BaYF5:Er3+, Yb3+ with Different Morphology for the Enhancement of Upconversion Luminescence
In this work, Er3+/Yb3+-codoped BaYF5 with different sizes and shapes have been synthesized by a simple solvothermal method. By changing the fluoride source, pH value, solvent, surfactants, Yb3+ concentration, temperature, and reaction time, the optimum synthetic conditions of BaYF5:Er3+, Yb3+ were found to improve the upconversion luminescent properties. It is found that the emission intensity...
متن کاملLu3+/Yb3+ and Lu3+/Er3+ Co-doped Antimony Selenide Nanomaterials: Synthesis, Characterization, Electrical, Thermoelectrical and Optical Properties
Lu3+/Yb3+ and Lu3+/Er3+ Co-doped Sb2Se3 nanomaterials were synthesized by a Co-reduction method in hydrothermal condition. Powder XRD patterns indicate that the LnxLn′xSb2-2xSe3 Ln: Lu3+/Yb3+ and Lu3+/Er3+ crystals (x= 0.00-0.04) are isostructural with Sb2Se3. The cell parameters were increased for compounds upon increasing the dopant content (x). SEM and TEM images show that Co-doping of Lu3+/...
