Theoretical Investigation of Energy Levels Splitting of CsCdBr₃:Pr³⁺ Crystal

Abstract:

Based upon the single electron energy state information and the combination of Racah’s group-theoretical consideration with Slater’s wavefunctions, the 91×91 complete energy matrix of 4f² configuration ion Pr³⁺ in C_3v crystal field has been constructed. The calculated Stark energy levels of CsCdBr₃:Pr³⁺ present a good agreement with the experimental values, which implies that the complete energy matrix method can be received as a recommendable tool to perform a theoretical analysis to the doped crystal. Besides, the influence of Pr³⁺ ions on the energy levels splitting of the host crystal CsCdBr₃ has been compared with two doped trichlorides by Pr³⁺ ions, which indicates that the sixth order crystal field parameters play an indispensable role in splitting the energy levels.
