本文描述了11个铀酰矿物加热后的显微荧光特征,并对实验结果进行了初步探讨。随着温度的升高,其相对荧光强度均有不同程度的衰减直至猝灭,但衰减的速度和猝灭的温度是各不相同的。热至200℃时测量的荧光光谱和常温下的荧光光谱相比,不同矿物变化也各不相同。本文根据实验结果绘制了荧光和温度关系曲线及加热至200℃时的荧光光谱曲线。这种荧光变化可能与加热后矿物失水和晶体结构变化有关。对鉴定铀酰矿物具有重要的意义。
This paper describes the microscopic fluorescence characteristics of 11 uranyl minerals after heating, and the experimental results are discussed preliminarily. As the temperature increases, the relative fluorescence intensity decays to different degrees until quenching, but the decay rate and the quenching temperature are different. Fluorescence spectra measured at temperatures up to 200 ° C vary from mineral to mineral at room temperature. In this paper, we plotted the relationship between fluorescence and temperature and the fluorescence spectra when heated to 200 ℃ according to the experimental results. This change in fluorescence may be related to mineral dehydration and changes in crystal structure after heating. The identification of uranyl minerals is of great significance.
