Abstract:

Pyrochlore type of lanthanum zirconate powder was prepared by Sol-Gel method using LaCl3 and ZrClO2·8H2O as raw materials, ethanol and deionized water as solvents, and the template P123 was introduced to control the pore structure in the powder. XRD, SEM and BET were used to determine the powder structure and morphology, and the luminescence property of Eu 3+ doped lanthanum zirconium samples were measured by fluorescence spectra. The results show that the introduction of template P123 is helpful to increase the number of large pores. When 6.56 g·mL -1 of P123 was used in the solution, there are lots of pores in the lanthanum zirconate particles, which have an average size of 43 nm and average capacity of 0.15 cm 3·g -1. The luminescence property of Eu 3+ doped lanthanum zirconium samples were significantly enhanced, and the quenching concentration increased from 9mol% to 11mol%.
