摘要
测定了TAP晶体中铊离子的价态,发现TAP晶体中除了一价的铊离子Tl+外,还有少量三价铊离子Tl3+的存在.实验还测定TAP晶体中存在的金属离子杂质,总量为0207mg/g.联系TAP结构的特点讨论了TAP晶体存在Tl3+和金属离子杂质是产生TAP晶体结构缺陷的重要原因。
The valence states of thallium ions in TAP crystal have been determined. It is shown that besides Tl +, there is a small number of Tl 3+ ions in TAP. The metal-ions impurities, the total of which is about 0 207mg/g, have been measured. In this paper, taking into account the features of the structure in TAP, we find that the exiting Tl 3+ ions and metal-ions impurities are the important reason for structure defects in TAP. The reason that the dislocation line runs parallel to c axis is analyzed as well.
