Abstract

YAlO

:Pr

is a good candidate for various luminescent applications. The crystal field parameters and energy levels of Pr

doped YAlO

are studied via a least-square optimization of the calculated to the measured energies of the 4f

levels using the f-shell computer program. The optimization procedure requires the initial values of all the parameters appeared in the 4f

effective Hamiltonian. The initial values of the free ion parameters are taken from those of Pr

in LaF

and those of the crystal field parameters are taken from those of Nd

in YAlO

. All the 4f

energy levels of Pr

are then calculated using the parameters obtained via the optimization procedure. Comparing the crystal field parameters of Pr

to those of Nd

and Er

in YAlO

it is found that the majority of the modules of the crystal field parameters decreases with increasing nuclear charge of the rare-earth ions.
