![]() ![]() Eu 3+ doped YVO4 nanoparticles with and without YVO4 shell have been. The two-step hydrothermal method is adopted YVO4: Eu<3+> nano-luminescent granule is hydrothermally synthesized in water at 250 DEG C. and optimum emission studies in luminescence of coreshell nanoparticles.The particle size of the phosphor powder is 30 to 100 nanometers. The mol ratio of the core of YVO4: Eu<3+> and the shell of YPO4 is 1:2-8:1. The surface morphology and roughness of the microspheres can be flexibly tuned by controlling the multistep interface deposition process and subsequent calcination temperatures. The molarity of the core europium of YVO4: Eu<3+> is 1 to 8 percent.The obtained microspheres possess a typical core-shell structure, large magnetization, and strong fluorescence emission. The two-step hydrothermal method is adopted YVO4: Eu<3+> nano-luminescent granule is hydrothermally synthesized in water at 250 DEG C. The mol ratio of the core of YVO4: Eu<3+> and the crust of YPO4 is 1:2-8:1. In this study, bifunctional core-shell magnetic fluorescent microspheres have been synthesized via a facile interface Pechini-type sol-gel method using citric acid and polyethylene glycol as chelating agent and cross-linking agent, respectively. The molarity of the core europium of YVO4: Eu<3+> is 1 to 8 percent.The emission properties of colloidal solutions of YVO4:Eu nanoparticles have. 425-431 ISSN: 0021-9797 Subject: citric acid, cross-linking reagents, fluorescence, humans, magnetism, microparticles, polyethylene glycol, roughness, sol-gel processing Abstract: Latent fingerprint recognition technique has received increasing attention because it helps to precisely identify human information for many applications.

Alghamdi, Yonghui Deng Source: Journal of colloid and interface science 2022 v.605 pp. ![]() The thickness of shells could be easily controlled by changing the number of deposition cycles (20 nm for one deposition cycle). 300 nm), smooth surface and non-agglomeration. ![]() Such nanobelts can grow along the 010 direction. The thickness, widths, and lengths of YVO4 nanobelts are about 4060 nm, 110180 nm, and several micrometers, respectively. A facile construction of bifunctional core-shell magnetic fluorescent microspheres for latent fingerprint detection Author: Panpan Pan, Tong Zhang, Bingjie Yu, Rongliang Ma, Qin Yue, Abdulaziz A. The obtained core-shell phosphors have perfect spherical shape with narrow size distribution (average size ca. A YF3 core-shell layer around YVO4:Eu nanoparticles partially recovers the intensity of the Eu³ emission. YVO4 and YVO4:Eu3+ nanobelts and polyhedral micrometer crystals have been successfully synthesized by hydrothermal treating the mixture of NH4VO3 and Y(NO3)3 without the aid of any surfactants and templates. ![]()
