Laser Excited Luminescence of Tb3+, Eu3+-Activated Ferroelectric Gadolinium Molybdate (GMO)
Gadolinium molybdate, Gd2(Mo04)3 (GMO), a ferroelectric-ferroelastic material exhibits interesting electrical and optical properties. Stimulated emission (1) has been obtained in this material with Nd3+ ions. However the spectroscopic properties of this material activated with Tb3+ and Eu3+, are not well known. In this paper some anomalous luminescence properties of a single domain GMO crystal activated with Tb3+ and Eu3+ are discussed. The excitation was accomplished directly by the 4f-4f absorption lines of the rare earth ions using a linearly polarized argon laser.
