Microwave-Assisted Synthesis Cd Metal Hexagonal Nanosheets

Sodium borohydride (NaBH4) as reducing agent, oleic acid (OA) as surfactant, deionized water as the dispersant, reducing cadmium nitrate (Cd(NO3)2 · 4H2O) can get Cd nanosheets by microwave method. Room temperature photoluminescence (PL) spectrum for Cd nanosheets recorded under xenon light wavelength of 325 nm exhibited obviously emission bands at 331, 379, and 390 nm. By analyzing the results of XRD and TEM, the nanosheets are thought as hexagonal phase and the size is about 20 nm. This synthesis performs in a lower temperature. Moreover our method is quite simple and the cost of the experiment is relatively lower.
