The article was titled 《Six-photon upconverted excitation energy lock-in for ultraviolet-C enhancement》, and you may find the article in Nature Communications.Recommanded Product: 1,3-Diphenylisobenzofuran The information in the text is summarized as follows:
Photon upconversion of near-IR (NIR) irradiation into UV-C (UVC) emission offers many exciting opportunities for drug release in deep tissues, photodynamic therapy, solid-state lasing, energy storage, and photocatalysis. However, NIR-to-UVC upconversion remains a daunting challenge due to low quantum efficiency. Here, we report an unusual six-photon upconversion process in Gd3+/Tm3+-codoped nanoparticles following a heterogeneous core-multishell architecture. This design efficiently suppresses energy consumption induced by interior energy traps, maximizes cascade sensitizations of the NIR excitation, and promotes upconverted UVC emission from high-lying excited states. We realized the intense six-photon-upconverted UV emissions at 253 nm under 808 nm excitation. This work provides insight into mechanistic understanding of the upconversion process within the heterogeneous architecture, while offering exciting opportunities for developing nanoscale UVC emitters that can be remotely controlled through deep tissues upon NIR illumination. The experimental part of the paper was very detailed, including the reaction process of 1,3-Diphenylisobenzofuran(cas: 5471-63-6Recommanded Product: 1,3-Diphenylisobenzofuran)
1,3-Diphenylisobenzofuran(cas: 5471-63-6) can be used as a fluorescent probe for detection of superoxide anion radical (O2−) inside the membrane lipid layer by DPBF fluorescence quenching method. 1,3-Diphenylisobenzofuran(DPBF) can be used as quencher during the photoinactivation of TA-3 mouse mammary carcinoma cells containing hematoporphyrin.Recommanded Product: 1,3-Diphenylisobenzofuran
