摘要：

A general nonaqueous route has been applied for the preparation of lanthanide ordered nanocrystalline hybrid structures. In a simple one-pot reaction process, Ln(III) isopropoxides (Ln = Gd, Sm, Nd) were dissolved in benzyl alcohol and reacted in an autoclave between 250 and 300 degrees C. This approach leads to crystalline lanthanide oxide layers regularly separated from each other by organic layers of intercalated benzoate molecules. They display good thermal stability for temperature up to 400 degrees C. The gadolinium-based nanohybrids showed outstanding optical emission properties when doped with terbium( III) and europium(III).
