Luminescent metal–organic frameworks (MOFs) are used for the detection of organophosphorus pesticides (OPs) due to their large surface area and pore volume as well as their special optical properties. However, most self-luminescent MOFs are not only complex to synthesize and unstable in water but also feature a “turn-off” sensing system, which has highly restricted their practical applications in OP detection. Herein, a “turn-on” fluorescence sensor based on the guest-induced luminescence MOF Ru(bpy)32+@UiO-66 was constructed, which realized the sensitive detection of OPs through a dual-enzyme system for the first time. Compared with self-luminescent MOFs, Ru(bpy)32+@UiO-66 was not only more easily synthesized but also had higher chemical and photostability in water. In this strategy, by means of the hydrolysis of AChE and ChOx, H2O2 will be produced, which can oxidize Fe2+ to Fe3+, thereby quenching the fluorescence of Ru(bpy)32+@UiO-66. In the presence of OPs, the activity of AChE can be inhibited, resulting in the inability to generate H2O2 and Fe3+, which will turn on the fluorescence signal of Ru(bpy)32+@UiO-66. As a result, the Ru(bpy)32+@UiO-66 sensing system not only had high sensitivity for OPs detection but also possessed a satisfactory detection recovery rate for parathion-methyl in real samples, which provides a new approach for OP detection in food safety as well as environmental monitoring.

In recent years, rare earth ion and transition metal ion co-doped fluorescent materials have attracted a lot of attention in the fields of WLEDs and optical temperature sensing. In this study, I successfully prepared the dual-emission Mg3Ga2SnO8:Eu3+,Mn4+ red phosphors and the XRD patterns and refinement results show that the prepared phosphors belong to the Fd-3m space group. The energy transfer process between Eu3+ and Mn4+ was systematically investigated by emission spectra and decay curves of Mg3Ga2SnO8:0.12Eu3+,yMn4+ (0.002 ≤ y ≤ 0.012) phosphors and the maximum value of transfer efficiency can reach 71.2%. Due to the weak thermal quenching effect of Eu3+, its emission provides a stable reference for the rapid thermal quenching of the Mn4+ emission peak, thereby achieving good temperature measurement performance. The relative thermometric sensitivities of the fluorescence intensity ratio and fluorescence lifetime methods reached a maximum value of 2.53% K−1 at 448 K and a maximum value of 3.38% K−1 at 473 K. In addition, the prepared WLEDs utilizing Mg3Ga2SnO8:0.12Eu3+ phosphor have a high color rendering index of 82.5 and correlated color temperature of 6170 K. The electroluminescence spectrum of the synthesized red LED device by Mg3Ga2SnO8:0.009Mn4+ phosphor highly overlaps with the absorption range of the phytochrome PFR and thus can effectively promote plant growth. Therefore, the Mg3Ga2SnO8:Eu3+,Mn4+ phosphors have good application prospects in WLEDs, temperature sensing, and plant growth illumination. Full article
