稀土金属卤化物灯的光谱特性

Spectrum Character of Rare Earth Halide Lamps

稀土元素有其一定的特征谱线，它们在可见光区能够发射大量的密集线光谱，用不同比例的多元复合物制成的灯的光谱能量分析表明：光谱能量分布取决于填充元素成份及组成配比，选择适当组合的复合物，可能获得所需最佳光电参数的光源。

Rare earth elements have characteristic spectrum. They enable to emit a great deal of dense and linear visible light. Different compound composed of manifold metal halides are existed in some lamps, the results of spectrum analysis of these lamps show: distribution of spectrum energy depends on composition and ratio of elements full in lamps. It's possible for us to obtain some good quality light source by choosing acceptable compound halides.
