Upconversion emission of a Er3+-doped glass microsphere under 633 nm excitation
نویسندگان
چکیده
In this work, The TBS glass microspheres doped with Er3þ for morphology-dependent resonances of upconversion emission were designed. The glass sample components are 25TiO2–27BaCO3–8Ba(NO3)2–6ZnO2–9CaCO3–5H3BO3–10SiO2–7water glass-3Er2O3 (wt%), and the emission spectra of TBS glass and a TBS glass microsphere (about 48 mm in diameter) were measured under 633 nm excitation and discussed. The strong morphology-dependent resonances of upconversion luminescences in the microsphere were observed. The observed resonances could be assigned by using the well-known Lorenz–Mie Formalism. q 2003 Elsevier Ltd. All rights reserved.

The 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 کاملSpectroscopic properties and upconversion mechanisms in Er3+-doped fluoroindate glasses.
Fluorindate glasses containing 1,2,3,4 ErF3 mol % were prepared in a dry box under argon atmosphere. Absorption, Stokes luminescence ~under visible and infrared excitation!, the dependence of S3/2, I11/2, and I13/2 lifetimes with Er concentration, and upconversion under Ti-saphire laser excitation at l5790 nm were measured, mostly at T577 and 300 K. The upconversion results in a strong green em...
متن کاملSynthesis and luminescence properties of Er3+ doped Y(OH)3, NH4Y3F10, and YF3 nanocrystals.
Y(OH)3:Er3+ nanowires were synthesized by a hydrothermal method. Y(OH)3:Er3+ can convert into NH4Y3F10:Er3+ after fluorization, and NH4Y3F10:Er3+ can convert into YF3:Er3+ after being annealed. The structures of obtained Y(OH)3:Er3+, NH4Y3F10:Er3+, and YF3:Er3+ samples were pure hexagonal, cubic, and orthorhombic phase, respectively. Under 378-nm excitation, the three samples showed similar fea...
متن کاملTm3+ Modified Optical Temperature Behavior of Transparent Er3+-Doped Hexagonal NaGdF4 Glass Ceramics
Er3+-doped and Er3+-Tm3+-co-doped transparent hexagonal NaGdF4 glass ceramics are fabricated via melt-quenching method. The emissions of Er3+-doped NaGdF4 glass ceramics are adjusted from the green to red by varying the concentration of Tm3+ ion under the excitation of 980 nm. The spectrum, thermal quenching ratio, fluorescence intensity ratios, and optical temperature sensitivity of the transp...
