Luminescence Characteristics

Eu3+ doped yttrium hydroxide nanosheets were successfully synthesized from layer compound of Y2(OH)5NO3 doped by Eu3+. Firstly layer compound of Y2(OH)5NO3 doped by Eu3+ was obtained by hydrothermal reaction. After ion exchange reaction with SDS, the layer space became lager. Furthermore stable nanosheet sol was prepared after exfoliation. The structure of layer compound and nanosheets were determined by XRD, TEM. The luminescence properties of yttrium hydroxide nanosheets doped with Eu3+ were examined; the relationship between structure and spectra was discussed.

Anion Exchange Reaction

New types of ionic liquids (ILs) with an epoxy group on a piperidinium-type cation were successfully synthesized by the simple anion exchange reaction of a solid 1-allyl-1-(oxiran-2-ylmethyl)piperidinium bromide, which was designed in this study. Unfortunately, the physicochemical properties, e.g., viscosity and ionic conductivity, of the ILs were inferior to those of common ILs such as 1-ethyl-3-methylimidazolium tetrafluoroborate ([C2mim][BF4]) and 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide ([C4mim][Tf2N]). However, the resulting ILs are of great interest as reaction intermediates: For example, the epoxy group on the cation could react with various reagents, including CO2. Consequently, the modification of the cation structure in the ILs was possible. This is particularly interesting because it is very difficult to modify commonly used ILs. The approach established in this article will provide a favorable synthetic route for creating novel functional ILs in the future.
