Abstract

The paper reports study of complex structure of matrix emission of undoped and RE-doped PbWO4 crystals. Decomposition of the spectra shows contributions of five components at 410, 485, 520, 565, 635 nm in emission of all the investigated samples. Their relative contributions depend on RE doping. Observed effects of RE doping are the same for the crystals with different RE impurities. Structures of luminescent centres are discussed taking into account studied effects of the impurity RE ions on spectral characteristics of the matrix emission.

稀土杂质对钨酸铅晶体基体发射结构影响的研究

本文报道了未掺杂和掺稀土的PbWO4晶体基质发射的复杂结构。光谱分解表明，所有样品在410、485、520、565、635 nm处的发射光谱有5种组分的贡献。它们的相对贡献取决于稀土掺杂。稀土掺杂对不同稀土杂质晶体的观察效果是相同的。考虑杂质稀土离子对基体发射光谱特性的影响，讨论了发光中心的结构。
