为探究稀土元素用于发光类烟火药剂的可能性，以稀土硝酸盐为氧化剂、镁粉为可燃剂、淀粉为粘合剂，设计、制备了含Ce、Pr、Sm、Eu、Tb、Dy、Yb 7种稀土元素的烟火药剂。用瞬态分光辐射仪测定了各药剂的燃烧光谱。分析了各药剂的光谱分布。结果表明：药剂的负氧氧平衡越高，特征光谱辐射强度越大。含不同稀土元素药剂的特征辐射光谱分布区间有相似性。含Eu元素药剂的光谱辐射分布在红光区。

In order to explore the possibility of rare-earth elements usage in luminescent pyrotechnics, magnesium powder as com-bustion agent and starch as binder, seven kinds of pyrotechnic composites containing Ce, Pr, Sm, Eu, Tb, Dy and Yb as oxidants were designed and prepared.The combustion spectra of each pyrotechnic composite were recorded by a transient spectral radiom-eter.Their spectral distributions were analyzed.Results show that the higher the negative oxygen balance of pyrotechnic compos-ites, the greater the radiation intensity of characteristic spectum.The characteristic radiation spectra distribution region of pyrotech-nic composites containing different rare-earth elements is similar.The spectral radiation of pyrotechnic composites containing Eu distributes in red light region.
