Mechanoluminescence materials exhibit fascinating optical properties due to their energy harvesting and controllable release capabilities. SrAl2O4:Eu2+ (SAOE) has been extensively studied as a traditional mechanoluminescence material, however, the luminescence intensity enhancement mechanism of its remain an unresolved issue, which hinders development widespread application excellent phosphors. Herein, promising rare earth (Re3+ = Sm3+, Dy3+, Er3+, Tm3+) doping strategy was proposed achieve intense SAOE. By introducing different Re3+ ions manipulate level positions in SAOE phosphors, depth density electron hole traps can be tuned, resulting maximum SrAl2O4:Eu2+, Tm3+ is about 11-fold higher than that The governing trap distribution unveiled through thermoluminescence glow curve analysis functional theory calculations. Our research provides valuable guidance for designing high-performance phosphors opens up new opportunities multifunctional applications.
