初步的TlBr晶体光学参数测试可用于探测器晶体的选择。基本光谱区的吸收用于带隙宽度定义和确定同系杂质的存在。发光被应用于杂质和缺陷含量的研究。用TlBr晶体平板电极电离辐射探测器测量了~（241）Am的放射性核素能谱。总结了不同材料制备的TlBr探测器的能量分辨率，并对探测器参数测试结果和光学研究结果进行了比较。
It is shown that preliminary TlBr crystals optical parameters testing can be used for detector crystal selection. Absorption in fundamental spectral region was used for the band gap width definition and determination of homological impurities presence. The luminescence was applied for impurity and defects content study. Radionuclide spectra241Am were measured using the ionizing radiation detectors with planar electrodes made from TlBr crystals. The detector energy resolution for TlBr detectors produced from different row materials was summarized and the results of detector testing parameters and results of optical investigation were compared.
