摘要
为了寻找新的发光材料基质,我们研究了BiOBr和La_(1-x)Bi_(x)OBr体系的合成方法,用晶格参数测定法确定了该体系固相线以下的相区。一、溴氧化铋的制备Sillèn曾用BiBr_(3)溶液水解法制得纯净的BiOBr。用Br_(2)水和BiI^(3)一起加热也可以得到BiOBr。在真空中和200℃下使CBr_(4)与Bi_(2)O_(3)反应,所得到的是BiOBr和BiBr_(3)的混合物。
In order to seeking new possible phosphor hosts a method of synthesizing BiOBr and samples of the system La1-xBixOBr has been developed.The subsolidus phase relationships in that system have been determined by lattice parameter measurements.The solid solubility at 800℃in that binary system was confined to the regions within x-<0.45 and x>0.59.
