The Luminescence of Ce^(3+),Tb^(3+)Ions and Ce^(3+)-Tb^(3+)Ion Pairs in Sr_(4)Si_(3)O_(8)Cl_(4)The Luminescence of Ce^(3+),Tb^(3+)Ions and Ce^(3+)-Tb^(3+)Ion Pairs in Sr_(4)Si_(3)O_(8)Cl_(4)

研究了Ce^(3+)、Tb^(3+)、离子及Ce^(3+)-Tb^(3+)离子对在Sr_(4)Si_(3)O_(8)Cl_(4)基质中的发射光谱和激发光谱。初步讨论了Ce^(3+)、Tb^(3+)离子之间发光敏化的机理。

In this paper the emission and excitation spectra of Ce^(3+),Tb^(3+)ions and Ce^(3+)-Tb^(3+)ion pair in Sr_(4)Si_(3)O_(8)Cl_(4) were studied.Both the Ce^(3+)and the Tb^(3+)ions show strong luminescence in this host.The luminescence color of the Cc^(3+)is violet and that of Tb^(3+)is yellowish-green.When Sr_(4)Si_(3)O_(8)Cl_(4) was activated by Ce^(3+)-Tb^(3+)pair the luminescence of Tb^(3+)was enhanced remarkably by Ce^(3+).The mechanism of sensitization of Tb^(3+)by Ce^(3+)is discussed.
