A facile synthesis of SrWO4 nanobelts by the sonochemical method

SrWO4 nanobelts have been synthesized via a facile and fast sonochemical route. The samples were characterized by XRD, SEM and TEM techniques. Experimental results showed that the concentration of Na2EDTA and high-intensity ultrasonic irradiation played important roles in controlling the morphologies of SrWO4. Room-temperature photoluminescence of SrWO4 with various morphologies have also been investigated. Results showed that SrWO4 nanobelts possessed good photoluminescent properties, suggesting that SrWO4 nanobelts could be used in novel optoelectronic devices.
