Tetragonal tungsten bronze (TTB) structure Ba4La0.95-xEr0.05GdxTiNb9O30 (BLETN:Gd3+) with different Gd3+ concentrations have been synthesized, and their structural, up-conversion photoluminescence (UC-PL), dielectric, ferroelectric (FE), and magnetic properties have been investigated in this work. With the incorporation of Gd3+, it is found that a BLETN:Gd3+ system exhibits multifold responds to the external electric, magnetic, and optical stimuli. Specially, enhanced UC-PL intensity, obvious relaxor-like FE state, and paramagnetic (PM) feature have been simultaneously realized in this single phase TI13-type compound. It is believed that the BLETN:Gd3+ system involving bright UC emission and promising electromagnetic properties may act as a potential material for future multifunctional device applications.
