In order to control reaction temperature and reduce processing time, a new method of ultrasound irradiation with microwave\r\nheating was used to synthesize (Ca1-??, Ln??)MoO4:Eu3 (Ln = La, Gd; 0 < ?? < 0.5) phosphors at only 80�°C in 30 minutes.\r\nTheir crystal structures and morphologies which have been verified by X-ray diffraction (XRD) and scanning electron microscopy\r\n(SEM) exhibited gradual changes due to the insertion of lanthanide ions (La or Gd) in calcium molybdates. Codoping of\r\nlanthanum ions (?? = 0.2) would enhance the emission intensities that were supported by fluorescent spectrophotometry\r\n(FL).
