Controlled Synthesis and Photoluminescent Properties of Cu2O Microcrystals with Different Morphologies
Cu2O microcrystals with cubic, spherical, and octahedral morphologies were easily synthesized in aqueous solution under the assistance of ultrasonic irradiation. The obtained products were characterized by using X-ray power diffractometry (XRD) and field emission scanning electronic microscopy (FE-SEM). The morphologies of Cu2O microcrystals could be controlled by simply adjusting NaOH concentration. It is believed that the difference in the growth rate of Cu2O crystal facets led to the formation of different morphologies of microcrystals, which exhibited good room-temperature photoluminescence properties with new green emission peaks at 530 nm, making them have potential applications as phosphors and biolabels.
