Title: Divalent europium doped CaF₂ and BaF₂ nanocrystals from ionic liquids

Abstract

A new, facile and quick synthesis method for Eu²⁺ doped the alkaline earth fluorides was developed using ionic liquids as solvent, precursor and capping agent. Reductive atmosphere and very high temperatures were avoided, while still attaining the desired structure, small particle sizes and divalent oxidation state of the lanthanide. Here, this opens the door for the development of new Ln²⁺ doped nanomaterials. Here, the successful Eu²⁺ incorporation was proven by optical spectroscopic measurements which showed the spin and parity allowed f-d transitions of Eu²⁺ in CaF₂:Eu²⁺/BaF₂:Eu²⁺. 4f⁷-4f⁷ transitions could be observed at low temperatures (7 K).

ELECTRON PARAMAGNETIC RESONANCE OF Gd$sup 3+$ IN CaF$sub 2$, SrF$sub 2$, AND BaF$sub 2$ (in French)

Journal Article Sierro, J - Helvetica Physica Acta (Switzerland)

Electron paramagnetic resonance (EPR) measurements at room temperature were made on trivalent gadolinium ions in single crystals of CaF/sub 2/, SrF/sub 2/, and BaF/sub 2/ and also in natural fluorites. The effects of heat treatments and of hydrolysis at high temperature on the EPR spectra were studied. In CaF/ sub 2/ there are four sets of spectra, the first having cubic symmetry, the second having axial symmetry about the cubic axes, and the two others having axial symmetry about the body diagonals of the cube. The spectra with cubic syrnmetry arise from Cd/sup 3+/ ions substituted for Ca/sup 2+/ ionsmore »« less
Spectroscopy and laser properties of Nd sup 3+ -doped CaF sub 2 , SrF sub 2 and BaF sub 2

Conference Payne, S A ; Caird, J A ; Chase, L L ; ...

The optical properties of Nd{sup 3+} in CaF{sub 2}, SrF{sub 2}, and BaF{sub 2} have been investigated in order to determine if these materials are useful as laser-pumped amplifier media. The CaF{sub 2}:Nd crystal was found to not be useful because the impurities tend to cluster at very low concentration, leading to the formation of nonluminescent centers. On the other hand, the Nd{sup 3+} centers in BaF{sub 2} exhibit unacceptably low transition strengths. SrF{sub 2}:Nd appears to have adequate absorption strength, and, in addition, to have a remarkably long emission lifetime of 1280 {mu}s. A maximum doping of 0.20 atomicmore »« less

Sonochemical synthesis and luminescence properties of single-crystalline BaF{sub 2}:Eu{sup 3+} nanospheres

BaF{sub 2} nanocrystals doped with 5.0 mol% Eu{sup 3+} has been successfully synthesized via a facile, quick and efficient ultrasonic solution route employing the reactions between Ba(NO{sub 3}){sub 2}, Eu(NO{sub 3}){sub 3} and KBF{sub 4} under ambient conditions. The product was characterized via X-ray powder diffraction (XRD), scanning electron micrographs (SEM), transmission electron microscopy (TEM), high-resolution transmission electron micrographs (HRTEM), selected area electron diffraction (SAED) and photoluminescence (PL) spectra. The ultrasonic irradiation has a strong effect on the morphology of the BaF{sub 2}:Eu{sup 3+} particles. The caddice-sphere-like particles with an average diameter of 250 nm could be obtained with ultrasonicmore »« less

Journal Article Kate, O.M. ten, ; Energy Materials and Devices, Department of Chemical Engineering and Chemistry, Eindhoven University of Technology, Den Dolech 2, 5600MB Eindhoven ; Zhang, Z. ; ... - Journal of Solid State Chemistry

Optical data of Sm, Tb and Yb doped Ca{sub 2}Si{sub 5}N{sub 8} and Sr{sub 2}Si{sub 5}N{sub 8} phosphors that have been prepared by solid-state synthesis, are presented. Together with luminescence data from literature on Ce{sup 3+} and Eu{sup 2+} doping in the M{sub 2}Si{sub 5}N{sub 8} (M=Ca, Sr, Ba) hosts, energy level schemes were constructed showing the energy of the 4f and 5d levels of all divalent and trivalent lanthanide ions relative to the valence and conduction band. The schemes were of great help in interpreting the optical data of the lanthanide doped phosphors and allow commenting on the valencemore »« less

The possibility of gain among the 5d-4f transitions of the rare earth ions

Miscellaneous Lawson, J K

Although a wealth of information exists on the 4f-4f transitions of rare earth ions doped into solid-state materials, relatively little research exists on the 5d-4f transitions present in the same materials. We have studied the 5d-4f transitions of three rare-earth ions in a variety of materials in an attempt to evaluate the potential of the 5d-4f transition as a laser transitions. We have measured the pump-probe spectrum of Sm{sup 2+}:CaF{sub 2} over a wide spectral region in order to characterize a material know to lase on a 5d-4f transition. We then measured comparable pump-probe spectra for Sm{sup 2+} in SrF{submore »« less
