中文摘要	Phosphors with (Ce0.67-xGdxTb0.33)MgAl11O19(0less than or equal toxless than or equal to0.37) composition were prepared by sol-gel processing. The preparation process, crystal structure and luminescent properties of the phosphor powders were investigated. The excitation spectrum is characteristic of Ce3+ ion, while the emission spectrum is composed of lines from Tb3+ ion with main emission peaks at around 542 nm and 487 nm. As the Gd3+ concentration increases, the luminescent intensity at about 542 nm increases to a maximum when x is about 0.12 and then decreases again at higher concentration of Gd3+ ion whereas, the luminescence at about 487 nm follows the contrary rule.
