A set of selection rules is deduced for the 4f2 transitional levels that mix with explicit 4f5d components. Based on these selection rules the dipole-allowed transitions between the 4f2 crystal field levels are determined in Pr3+ doped SrAl12O19. Meanwhile
the main 4f5d components mixed into 4f2 transitional levels are identified by determining the nonzero matrix elements of both the odd-rank crystal-field and the electric dipole operator. The selection rules have been applied to analyze the transitions from 1S0 and 3P0 to lower crystal field levels. 2006 Elsevier B.V. All rights reserved.
