Abstract

Details of preparation, spectroscopic and structural studies along with crystal field calculations for two Cr³⁺ doped spinels MgAl₂O₄ and ZnAl₂O₄ are given in the present paper. Both compounds show efficient red emission at about 685 nm, which is due to the ²E_g → ⁴A_2g spin-forbidden transition of Cr³⁺ ions located at the sites with D_3d local symmetry. Analysis of structure of the CrO₆ clusters was performed; comparison of the crystal field effects in both compounds revealed that the low-symmetry splitting of the orbital triplet states is more pronounced in ZnAl₂O₄. Both compounds show potential for applications as red-emitting phosphors.
