Self-trapped exciton (STE) emissions based on Sb³⁺ ion materials have recently received widespread attention, due to the excellent photoluminescence (PL) properties and stereochemical activity of Sb³⁺ ions. Pressure can precisely regulate the electronic structure and configuration of chromophores, becoming an effective approach to enhance the STE emissions. Recently, STE emission enhancements in Sb³⁺-based materials under pressure mainly focus on metal halides, however, studies on inorganic oxides are very limited. Herein, the high-pressure STE behavior of SbTaO₄ was investigated up to 13.2 GPa. The STE emission exhibits a bi-peak feature, and the strongest emission occurs at 3.8 GPa, in which two peaks are enhanced by ~20 and ~3 times and the STE emission displays a bright green color. The mechanism is explained using a variety of methods, including steady-state PL spectroscopy, kinetic spectroscopy, Raman spectroscopy, cryogenic PL spectroscopy and theoretical calculations. It shows that the strong electron-phonon coupling of SbTaO₄ is weakened, which suppresses non-radiative transitions. Also, the distortion of the [SbO₄] unit inhibits the transition between two STE states. The synergistic effect of these factors leads to a strong enhancement of the STE emission in SbTaO₄ under pressure. The STE emission enhancement of SbTaO₄ highlights the potential of inorganic oxides for future high-pressure STE exploration and provides the promising material in photonic devices under extreme conditions.
