The fabrication of water-stable perovskite-europium hybrid polychromatic fluorescence nanosensor for fast visual sensing of tetracycline

Recent advances in synthesis of water-stable metal halide perovskites and photocatalytic applications

“…260 Instead of the time-consuming LBVD method, to form surface hydroxides may be obtained by simply adjusting the pH of metal halide precursor solution with ammonium hydroxide. 261,262 Such MAPbBr 3 @PbBr(OH) retained 89.9% of the initial PL value ( i.e. , 64.28%) after being immersed in water for 1 year (Fig.…”

Biomolecules incorporated in halide perovskite nanocrystals: synthesis, optical properties, and applications

“…6c and d). 201–204 FL quenching and enhancement may occur by means of several mechanisms such as structural alteration of HPNCs, charge and energy transfer, FRET, inner filter effect (IFE), photoinduced electron transfer (PET), and complex formation (Table 2). For example, the crystalline structure alteration and degradation of HPNCs has been applied to detect H 2 S in rat brain samples (Fig.…”

A perovskite‐based electrochemiluminescence aptasensor for tetracycline screening

“…Although these conventional large-scale instrument detection methods have high stability, sensitivity, and accuracy, they are complex, time-consuming, and expensive, making them unsuitable for onsite rapid detection. In recent years, various new sensing methods for antibiotic detection have emerged, such as fluorescence, photoelectrochemical catalysis, and colorimetric methods [9][10][11][12]. Wang For ECL detection, stable and efficient luminescent materials are crucial.…”
