Abstract

This paper reports the charge compensation effects of Al3+ incorporated ZnTiO3:Eu3+ as a co-dopant ion. The structural and morphological characterization show that the addition of Eu3+ and Al3+ does not affect the phase formation and the surface morphology of the host. There was an improvement in the luminescence emission intensity of Eu3+ ions for an optimal concentration of 2 mol% under 395 nm excitation, after incorporating Al3+ charge compensator. The energy level diagram showing the charge compensation mechanism was proposed for the co-doped system.
