摘要：

Nanoparticles of Cu2L2O, (L = Ho, Er) (15-25 nm in size) were synthesised by the intermediate use of W/O microemulsions. In this process the aqueous cores of water/cetyltrimethylammonium bromide/n-octane/1-butanol microemulsions were used as microreactors for the precipitation of Cu2Ho2(CO3)(4)(OH)(2) (25-30 nm) and Cu2Er2(CO3)(4)(OH)(2) (10-40 nm) as precursors. These mixed salts were separated and further decomposed to the corresponding mixed oxides at 900 degrees C for 16 h. All solids were characterised by scanning and transmission electron microscopy, IR, XRPD, ICP-OES, TCA, XPS measurements and elemental analyses. (C) 1999 Elsevier Science B.V. All rights reserved.
