摘要
The absorption spectra and fluorescence spectra of La_(1-x)Nd_(x)P5O_(14)(LNPP)glass were studied.The fluorescence from the Xlevel of interest^(4)P_(3/2)(1)state shows an exponential decay and linear concentration quenching.Time resolved fluorescence 1ine narrowing was observed for LNPP glass with different x values.For high x value LNPP glass,energy transfer between Nd^(3+)ions intraline was observed at low temperature.
