Abstract

Abstract: In this paper, uniform and dispersive CaSO_4·0.662H₂O nanorods were synthesized in reverse micellae (W/O microemulsion) containing AEO, cyclohexane, and n-pentanol. The average diameter and length were 50nm and 800~-1600nm respectively. The study of the preparation conditions showed that the preferred synthesis conditions were: ω(H₂O/surfactant)=6~15, γ(oil/surfactant)=5~12 and the reactant concentration 0.05~0.3mol/L. The property study showed that nano calcium sulphate could produce stronger purple light emission at 339nm. This property would have a very expansive application prospect in the fields of nano-electric devices and so on.

Key words: calcium sulphate, nanorods, reverse micelles, soft template
