Facile Synthesis and Photoluminescence of Calcium Sulphate Nanorods

Zhang Xiu, Li Li

Abstract

In this paper,uniform and dispersive CaSO_4-0.662H_2O 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 prepa- ration conditions showed that the preferred synthesis conditions were:ω(H_2O/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.
