摘要

Lanthanum magnesium hexaaluminate (LaMgAl_(11)O_(19), LMA) has attracted much interest as its widely used in solid state lasers, TV phosphors and fluorescent lamps. In this paper, LaMgAl_(11)O_(19) ceramic was pressureless sintered at 1650 °C for 10 h in air atmosphere using LaMgAl_(11)O_(19) powders prepared by solid-state reaction at 1500 °C for 4 h. The result indicated that the synthesis temperature of LaMgAl_(11)O_(19) powders was about 1500 °C. The LMA ceramic sample was dense and had a microstructure of platelet-like gains. The excitation spectrum shows two wide bands with the peaks at about 254 nm and 265 nm by monitoring the strongest 362 nm emission, and the emission spectra is consisted of a broad band emission with their peaks near 362 nm with a half-width about 5 nm exciting with 265 nm wavelength.
