Lanthanide-containing persistent luminescence materials with superbright red afterglow and excellent solution processability

Abstract

Lanthanide-containing persistent luminescence materials are promising candidates for a wide range of applications by virtue of splendid superiorities in afterglow performance. However, it is a crucial challenge to achieve high-quality afterglow materials at the attractive nanoscale, with uniform size, controllable morphology, and satisfying brightness. Herein, a bottom-up approach was developed to construct the high-quality afterglow nanoparticles, incorporating luminescent lanthanide complex and organic molecular ingredients under mild conditions. These nanoparticles exhibited intrinsic lanthanide luminescence with superbright red afterglow (>10 cd m −2 ) in a homogeneous solution. The afterglow solution with excellent processability can serve as ideal building blocks for the on-demand fabrication of functional nanomaterials. Water-dispersible afterglow nanoparticles with stateof-the-art high brightness were uniformly constructed to perform whole-blood lateral flow assay of procalcitonin with a nakedeye detection limit of 0.5 ng mL −1 , promoting the point-of-care testing development.

Review of Mn-Doped Semiconductor Nanocrystals for Time-Resolved Luminescence Biosensing/Imaging

“…A possible approach is to develop nanocomposites integrating multiphase materials in a nanoscale domain to gain collective or novel material characteristics from individual components. Recently, organic after-glowing materials with long luminescence lifetimes (up to seconds) are emerging for biomedical applications. − These materials usually emit the blue-to-green color range. , There may be a good opportunity to couple these organic after-glowing materials with Mn-doped NCs to achieve new nanocomposites that possess orange or red Mn emission but the longer lifetime of organic after-glowing materials. Additionally, Mn-doped NCs can be conjugated with organic NIR dyes to achieve NIR emission with a millisecond lifetime through Förster resonance energy transfer.…”

Ultra‐long Near‐infrared Repeatable Photochemical Afterglow Mediated by Reversible Storage of Singlet Oxygen for Information Encryption

“…In addition, since all the components are highly modular, on-demand designed photochemical afterglow systems in all types are accessible via powerful wet-chemical methods. To date, multifarious photochemical afterglow systems have been successfully designed and applied for bioimaging, [11] biological theranostics, [12] in vivo temperature sensing, [13] immunochromatography, [14] information encryption, [15] etc.…”

Efficiently predicting and synthesizing intrinsic highly fire-safe polycarbonates with processability

“…21–23 However, these structures, in turn, lead to inflexible material status and inevitably poor processing and limited practicability. 24–26 For a long time, scientists have been struggling to solve this dilemma by developing new materials to balance the fire-safe performance and processability, simultaneously, via scientific intuition and trial-and-error experiments. Unfortunately, this paradigm is time consuming and less efficient.…”
