| 英文摘要 | Mechanoluminescence (ML) phosphors have made significantprogressin various fields, such as artificial intelligence, the Internet ofThings, and biotechnology. However, enhancing their weak ML intensitystill remains a challenge. Here, we report a new series of Na1-x Mg x NbO3:Pr3+ (x = 0.00, 0.10, 0.20, 0.40,0.60, 0.80, and 1.00 mol %) heterojunction systems, which exhibitsignificant ML enhancement as compared with either the Pr3+-doped NaNbO3 or MgNbO3, and the physical mechanismsbehind the ML enhancement have been explored comprehensively fromboth the experiment and theory points of view. Experimental tests,including thermoluminescence and positron annihilation lifetime measurements,combined with first-principles calculations, consistently indicatethat the ML enhancement observed in these newly reported systems isdue to the formation of heterojunctions, which plays a crucial rolein modulating the defect configuration of the phosphors and facilitatingefficient charge transfer. By controlling the Na/Mg ratio in conjunctionwith Pr3+ doping, continuous changes in the band offsetand the concentrations of certain types of traps in the forbiddengap are achieved, leading to the optimum conditions in the 8/2 ratiosamples. These findings demonstrate a novel type of ML phosphor andprovide a theoretical basis for the design of high-performance MLphosphor. |
