Self-charging persistent mechanoluminescence (SC-PML) is of particular interest for stress sensing/visualization applications, as it not only notably extends the time window available for stress observation, but also avoids the pre-charging with great convenience. However, the intrinsic physical principles of the SC-PML are still unclear. Herein, a phosphor SrLiMg(PO): Dy with an initially clean trap structure is reported to exhibit repeatable SC-PML up to 30 s when incorporated into a flexible polydimethylsiloxane.

In this study, we aimed to clarify the impact of berberine hydrochloride (BH), the hydrochloride form of an isoquinoline alkaloid, on the control efficiency of citrus sour rot and its antifungal mode against G. citri-aurantii.

In this phosphor, Cr acts as the energy absorber (250-700 nm) to sensitize Yb/Nd in LaGaGeO. Under excitation at 418 nm, LaGaGeO:Cr, Yb phosphors exhibited a broad emission band in the near-infrared (NIR) region located at 976 nm (LaGaGeO:Cr, Nd at 1056 nm), which was attributed to the F-F transition of the Yb ions (F → I transition of Nd).
