CaF2 nanocrystals doped with Yb3+, Tb3+ and Li+ ions were investigated to study the correlation between their structural, electronic and up-conversion emission properties. The role of interstitial and substitutional Li+ ions in enhancing the up-conversion intensities were discussed. Evidence of Li+ at both interstitial and substitutional sites was provided by X-ray diffraction and XPS. The diffuse reflection spectra confirmed that the dopants were successfully incorporated. Up-conversion emission spectra under 980 nm excitation wavelength revealed the vital role of Li+ ions in enhancing both blue and green emission. The results reported during this investigation are expected to provide better understanding of the mechanism involved in enhancing the up-conversion emission in many Yb3+-Tb3+ co-doped fluoride materials due to Li+ ions doping. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Electric Literature of ClLi).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Electric Literature of ClLi
