Luminescence of Li₂W_1-0.05Mo_0.05O₄ crystal was investigated under X-ray excitation. A broad emission band with a maximum at ∼530 nm was measured at temperature 8 K, two phosphorescence exponential components with decay constants 15 s and 380 s were observed after X-ray irradiation at the low temperature. Thermally stimulated luminescence (TSL) was recorded in Li₂W_1-0.05Mo_0.05O₄ crystal after X-ray irradiation at 8 K. Seven clear TSL peaks in the temperature region 8–150 K were observed. An equidistant character of the TSL peaks can be explained by oscillatory pattern for thermal-delocalization energies from traps. A delocalization energy value for the most intensive TSL peak at 21 K is calculated. It allowed estimation of the main parameters of the traps in the crystal (delocalization energies and frequency factors). The correspondence between the traps energy and the integer value of the crystal-lattice oscillatory-quanta energy indicates the direct tunneling of a charge carrier into an excited state of the recombination center located near the trap.

在X射线激发下研究了Li ₂ W _1-0.05 Mo _0.05 O ₄晶体的发光。在8 K温度下测得的最大发射带宽于530 nm，在低温X射线照射后观察到两个磷光指数成分，其衰减常数分别为15 s和380 s。Li ₂ W _1-0.05 Mo _0.05 O _4中记录了热激发发光（TSL）在8 K的X射线辐照后形成晶体。在8–150 K的温度范围内观察到七个清晰的TSL峰。TSL峰的等距特征可以用陷阱的热离域能量的振荡模式来解释。计算了21 K时最强的TSL峰的离域能值。它可以估算晶体中陷阱的主要参数（离域能和频率因子）。阱能与晶格振荡量子能的整数之间的对应关系表示电荷载流子直接隧穿到位于阱附近的复合中心的激发态。
