对梯度炉法生长的纯NaF晶体,在0℃并经严格避光进行电子束辐照着色。着色的晶体在室温至400℃范围内以20℃/分的恒定升温速率共得到七个TL峰,其峰值位置分别在77、97、142、160、210、254和372℃;相应命以Ⅰ～Ⅶ峰。按Chen理论计算了它们的激活能、频率因子和动力学级次。其中Ⅰ峰是经过光学再激发以后得到的,并伴随有热激电流峰,Ⅱ和Ⅲ峰对光学再激发敏感,Ⅵ和Ⅶ峰的退除将使晶体硬度明显下降,并且低温Ⅰ、 Pure NaF crystals grown by the gradient furnace method were electron beam-irradiated at 0 ° C and strictly protected from light. Seven TL peaks were obtained from the colored crystals at a constant heating rate of 20 ℃ / min from room temperature to 400 ℃, with the peak positions at 77, 97, 142, 160, 210, 254 and 372 ℃, respectively. ~ Ⅶ peak. According to Chen's theory, their activation energy, frequency factor and kinetic order were calculated. The Ⅰ peak is obtained after the optical re-excitation and accompanied by the heat shock current peak, Ⅱ and Ⅲ peak sensitive to optical re-excitation, Ⅵ and Ⅶ peak will make the crystal hardness dropped significantly, and low temperature Ⅰ,
