硝酸铕和铽与穴醚固体配合物的发光

Studies on Luminescence of Complexes of Rare Earth Europium and Terbium with Cryptand(2. 2)

应用荧光光谱研究了稀土硝酸铕和硝酸铽的穴醚配合物，结果指出配合物的发光强度强于稀土硝酸盐，说明有机大环配体穴醚能有效地吸收和传递能量给稀土离子．

The complexes of rare earth nitrates with cryptand (2. 2) have been investigated by fluoresence spectroscopy. The results of experiment show that the emission intensity of rare earth complexes is stronger than that of rare earth nitrates,it is known that the cryptand (2. 2) is able to absorb energy and transfer the energy to rare earth ions.
