Perovskite-Based Nanostructures for Fluorescence Afterglow Anticounterfeiting

ACS Applied Nano Materials, Год журнала: 2023, Номер 6(10), С. 8990 - 8998

Опубликована: Май 4, 2023

Advanced fluorescence anti-counterfeiting technology has attracted the attention of researchers and encourages people to develop more materials with colors functions. Here, in order achieve a full-band afterglow visible light region, we designed composite CsPbI3-CsPbBr3/Sr2MgSi2O7:Eu2+,Dy3+@SiO2, which is composed nanoscale all-inorganic cesium lead perovskite quantum dots (PQDs) long-afterglow luminescent Sr2MgSi2O7:Eu2+,Dy3+ (SMS). SMS used store energy, PQDs are control emission colors; through their energy transfer, can be adjusted region. SiO2 as coating material improve temporary stability nanocomposite. The mixed oleic acid (OA) dye, exhibits different emitting under excitation environments. This research provided an idea for using field by double afterglow.

Abstract Metal halide perovskites (MHPs) have shown great application prospects in the field of optoelectronics owing to their superior optical and optoelectronic properties. Bandgap engineering impurity doping are effective ways achieve regulation luminous properties visible light region. However, realizing efficient deep red wide‐range tunable near‐infrared (NIR) emission remains a challenge. Here, series rare earth (RE 3+ ) ions = Nd, Dy, Ho, Er, Tm, Yb) doped Cs 4 Cd 1− x Mn Sb 2 Cl 12 (0 ≤ 1) quadruple designed. An luminescence from NIR is achieved based on energy transfer (ET) 2+ RE by building bridge, which covers NIR‐I (650–900 nm) NIR‐II (900–1700 regions. Moreover, ET efficiency availably influenced concentration . Interestingly, bridge cut off because increased bandgap when Bi introduced into ‐doped 0.4 0.6 2− y 2) lattice.

Double Layer SiO₂-Coated Water-Stable Halide Perovskite as a Promising Antimicrobial Photocatalyst under Visible Light

Nano Letters, Год журнала: 2024, Номер 24(43), С. 13718 - 13726

Опубликована: Окт. 15, 2024

Halide perovskite nanocrystals (HPNCs) have emerged as promising materials for various light harvesting applications due to their exceptional optical and electronic properties. However, inherent instability in water biological fluids has limited use photocatalysts the aqueous phase. In this study, we present highly water-stable SiO2-coated HPNCs efficient antimicrobial applications. The double SiO2 layer coating method confers long-term structural stability water, while situ synthesis of lead- bismuth-based NCs into shell enhances versatility tunability. We demonstrate that substantial generation singlet oxygen via energy transfer from enables photoinduced antibacterial efficacy under conditions. More than 90% Escherichia coli was inactivated mild visible irradiation 6 h. excellent photocatalytic performance suggests hold great potential phase

Emergence of Quantum Dots as Innovative Tools for Early Diagnosis and Advanced Treatment of Breast Cancer

ChemMedChem, Год журнала: 2024, Номер 19(16)

Опубликована: Май 10, 2024

Quantum dots (QDs) semiconducting nanomaterials, have garnered attention due to their distinctive properties, including small size, high luminescence, and biocompatibility. In the context of triple-negative breast cancer (TNBC), notorious for its resistance conventional treatments, QDs exhibit promising potential enhancing diagnostic imaging providing targeted therapies. This review underscores recent advancements in utilization techniques, such as fluorescence tomography magnetic resonance imaging, aiming at early precise detection tumors. Emphasis is placed on significance QD design, synthesis functionalization processes well use innovative strategies drug delivery, capitalizing ability selectively deliver therapeutic agents cells. As research this field advances rapidly, covers a classification according composition, characterization techniques than can be used determine properties and, subsequently, emphasizes findings TNBC-targeting, highlighting imperative need address challenges, like toxicity or methodologies standardization. Collectively, explored thus far suggest that could pave way diagnosis effective therapy TNBC, representing significant stride toward personalized treating TNBC.
