| Abstract: | A new material of Zr_(0.1)Al_(1.9)Mo_(2.9)V_(0.1)O_(12) is synthesized by the traditional solid state synthesis method. The phase transition, coefficient of thermal expansion, and luminescence properties of Zr_(0.1)Al_(1.9)Mo_(2.9)V_(0.1)O_(12) are explored with Raman spectrometer, dilatometer, and x-ray diffraction(XRD) diffractometer. The results show that the Zr_(0.1)Al_(1.9)Mo_(2.9)V_(0.1)O_(12) possesses the strong broad-band luminescence characteristics almost in the whole visible region.The sample is crystallized in a monoclinic structure group of P2_1/a(No. 14) crystallized at room temperature(RT). The crystal is changed from monoclinic to orthorhombic structure when the temperature increases to 463 K. The material has very low thermal expansion performance in a wide temperature range. Its excellent low thermal expansion and strong pale green light properties in a wide temperature range suggest its potential applications in light-emitting diode(LED) and other optoelectronic devices. |
