![]() ![]() The biocompatibility and drug release evaluations indicate the potential biological applications of the samples. Preparation and properties of multifunctional Fe 3 O 4 YVO 4:Eu 3+ or Dy 3+ core-shell nanocomposites as drug carriers. Herein, we develop a novel sensitive fluorescent probe with an open core/shell nanostructure (OCSNS), rod-Y2O3:Eu3+0.01YVO4:Eu3+, in which a YVO4:Eu3+. Semantic Scholar extracted view of Comparing the luminescence processes of YVO4:Eu and core-shell YVO4YF3 nanocrystals with bulk-YVO4:Eu by L. ![]() Typically, red emission of YVO 4:Eu 3+ predominated under 465 nm excitation the upconversion spectra of YVO 4:Yb 3+, Er 3+ and YVO 4:Yb 3+, Ho 3+ revealed green and red color upon 980 nm excitation, respectively. The luminescence intensity and lifetime of those samples were less than those of their counterpart core samples. The silanol group (SiOH) is present in silica coated samples (heated up to 500 ☌) and acts as luminescence quencher. Method Synthesis and Characterization of YVO4:Eu3+YPO4 Core-shell Phosphor. Mesoporous core–shell structured (Y, Gd)VO 4:Ln 2 were designed to improve the properties for drug release. Successful coating of the silica on the YVO 4:Ln 3+ core could be observed by transmission electron microscopy. In order to improve the stability and luminous efficiency of YVO4:Eu3+. The control of particle size for hollow (Y, Gd)VO 4 was realized, facilitating their practical application. Monodisperse ellipsoid-like hollow (Y, Gd)VO 4 were designed by employing (Y, Gd)(OH)CO 3 colloidal spheres as a sacrificial template and NH 4VO 3 as a vanadium source, and the formation mechanism could be interpreted by the Kirkendall effect. We have carried out extensive neutron inelastic scattering experiments to derive the phonon dispersion relation of YVO4 up to high energy transfer of 65 meV using a single crystal, which are perhaps reported for the first time in any orthovanadate compound. In this paper, size-controlled morphologies of (Y, Gd)VO 4 and (Y, Gd)VO 4:Ln 3+ (Ln = Eu, Yb, Er, and Ho) were obtained via a facile hydrothermal route, and their properties for drug delivery and photoluminescence were investigated. and further deposition of phosphors (down-conversion YVO4:Eu3+ or up-conversion NaYF4 :Yb,Er/Tm phosphor nanocrystals) on the core-shell nanoparticles. ![]()
