Structural characterization, luminescence properties and applications of Eu³⁺ ion-doped bismuth molybdate phosphor via a molten salt-assisted approach

A molten salt-assisted method for the synthesis of Eu3+-doped bismuth molybdate (BMO: Eu3+) phosphor was proposed. (BMO: Eu3+) phosphors with different phase structures were obtained by changing the calcination temperature. The applications in LED devices and latent fingerprint recognition of the obtained product were explored. The results of structural characterizations and scanning electron microscope (SEM) photographs analysis prove that the products exhibit different crystal structures and morphologies with the change of calcination temperature. Based on the above findings, the as-prepared products have potential applications in the field of WLED and potential fingerprint recognition.
