Stimuli‐Responsive Lanthanide‐Based Smart Luminescent Materials for Optical Encoding and Bio‐applications

Abstract

Lanthanide based luminescent materials have attracted extensive attention in a wide range of fields including chemistry, biology and logic due to the narrow emission band, long decay time of the excited state, low auto‐fluorescence background and excellent photostability. More interestingly, stimuli‐responsive lanthanide‐based luminescent materials have exhibited enormous application prospects in optical encoding and bio‐applications. In this review, we summarize these aspects of the development of stimuli‐responsive smart lanthanide luminescent materials by sorting the stimuli into several categories, including photo‐, pH‐, thermo‐ and molecule‐responsive. These unique stimuli‐responsive properties endow these materials with great potential in enriching code library and expanding data storage. Additionally, these properties have also been studied widely for bio‐applications, including drug release, imaging biosensing, cell adhesion, and cancer therapy. Based on these two aspects, we highlight the recent progress of lanthanide‐based smart luminescent materials.

Metal-Organic Framework-Based Stimuli-Responsive Polymers

“…The last category of MOFs is SRPs capable of altering their properties under multiple stimuli. In addition, there are other comprehensive reviews on the topic of MOFs in a different perspective that the readers can refer to [14][15][16][17][18][19][20][21][22][23][24].…”

Eu-phen Bonded Titanium Oxo-Clusters, Precursors for a Facile Preparation of High Luminescent Materials and Films

“…Numerous Eu-based compounds and materials have been prepared. In addition to the design and synthesis of more efficient luminescent antenna complexes and the study of their photophysical properties, − recent focus has been on Eu-based smart materials (organic–inorganic hybrid films, nanoparticles, and polymers) for luminescent optical devices and bioapplications. , The full exploitation of the Eu-complexes in practical applications has been hampered by their inherent drawbacks like poor mechanical and unrecoverable properties as well as quenching due to the tendency to aggregate. Incorporating Eu complexes into various matrixes to prepare luminescent hybrid materials is one of the acceptable strategies to overcoming the aforementioned shortcomings.…”

Controlling and Predicting the Dissolution Kinetics of Thermally Oxidised Mesoporous Silicon Particles: Towards Improved Drug Delivery

“…More than 20 years after the initial discovery of porous silicon (pSi) photoluminescence by Professor Canham, and his subsequent work on the fabrication of bioactive pSi [1], there remains significant ongoing interest in its biomedical applications, including therapeutic delivery, medical imaging, and theranostics [2][3][4][5][6][7][8][9][10][11][12][13]. PSi possesses a highly tuneable porous nanostructured network and can be fabricated into a variety of different forms, ranging from thin films [14], nanowires [15], and micro-and nanoparticles [6,[16][17][18].…”
