Bhobe利用稀土离子与荧光素直接反应,制备了配合物,并研究了它们的电学性质。本文采用了与之不同条件合成了镧、铈、镨、钕、钐、铕、钇等稀土的荧光素、二溴荧光素配合物,研究了它们的电阻率与温度的变化关系。 稀土荧光素配合物的制备是先取9.4克荧光素二钠盐于烧杯中,加入1.3克荧光素,在 Bhobe utilizes the direct reaction of rare earth ions with fluorescein to prepare the complexes and studies their electrical properties. In this paper, different concentrations of fluorescein and dibromofluorescein complexes of lanthanum, cerium, praseodymium, neodymium, samarium, europium, yttrium and other rare earths were synthesized under different conditions and the relationship between their resistivity and temperature was studied. Preparation of rare earth fluorescein complex is to take 9.4 grams of fluorescein disodium salt in a beaker, adding 1.3 grams of fluorescein, in
