Description

Description générale

Cerium magnesium aluminate, terbium doped is a phosphor material, which has a magnetoplumbite structure and luminesces effectively in the UV region. The addition of terbium allows the transfer of excitation energy from Ce³⁺ to Tb³⁺, resulting in the formation of green luminescence. It can be prepared by methods such as spray pyrolysis and combustion method.[1]
