摘要

In the Pr(3+)-doped Y(2)SiO(5), the population in (1)D(2) of Pr(3+) can be transferred to (3)P(0) State via non-radiative energy transfer by the laser excitation in resonance with (3)H(4) --> (1)D(2), and we can experimentally study the Stark splitting of (3)H(4) energy level via (3)P(0) --> (3)H(4) anti-Stokes emission spectra. Because the anti-Stokes emission spectra can avoid the energy transfer between different crystallographic site (1)D(2) energy levels, the above splitting lines attribution is more accurate than the assignment via (1)D(2) --> (3)H(4) Stokes spectra by the laser excitation in resonance with (3)H(4) --> (1)D(2). In addition, the character of the anti-Stokes fluorescence decay time was observed.
