Abstract

Decahedral CdMoO4 microcrystals have been synthesized by a reaction for 48 hours at 60 o C from CdCl 2 and Na 2 MoO4 in he presence of 4 mL ionic liquid 1n butyl 3 methylimidazolium chloride ([BMIM]Cl) as a sur factant. Powder X ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the structure and morphology of the microcrystals. The photoluminescence (PL) spectrum of the as synthesized decahedral CdMoO4 microcrystals exhibits a strong and broad emission at visible zone. A plausible formation mechanism of decahedral CdMoO4 microcrystals was discussed in detail and evaluates as a typical Ostwald Ripening process. It is expected that this method can be extended to the fabrication of other microcrystals of metallic salts..
