Multiresponsive Emissions in Luminescent Ions Doped Quaternary Piezophotonic Materials for Mechanical‐to‐Optical Energy Conversion and Sensing Applications

Abstract

Visualization and noncontact sensing can be achieved based on multimode luminescent materials, which is essential to flexible optoelectronics, information encryption, and infrastructure monitoring. However, the development of optical sensors is primally limited by developing high-performance luminescent functional materials with energy conversion. Here, by codoping transition metal and lanthanide ions into quaternary piezophotonic semiconductors MZnOS (M = Ca, Sr, Ba) microcrystals, the efficient multimode luminescent materials are successfully synthesized. They can simultaneously respond to ultraviolet, near-infrared and stress, and exhibit completely different optical characteristics. Specifically, both composite film and block are prepared by mixing luminescent particles and polymers for mechanical-to-optical energy conversion. The developed composite based on mechanoluminescence can be utilized for visualizing pressure distribution, even E-signature, and anti-counterfeiting systems. In addition, temperature detection is researched based on upconversion emissions. The results suggest that these materials have great potential applications in advanced optical multimode sensors, which is of significance for integrated optoelectronic devices.

N-alkylation briefly constructs tunable multifunctional sensor materials: Multianalyte detection and reversible adsorption

“…The multianalyte detection concept, which was first proposed by De Silva's group ( Magri et al., 2006 ; Schmittel and Shu, 2012 ; Chen et al., 2015 ; Magri, 2021 ), has become a hotspot in the field of sensors owing to its advantages of high efficiency, rapidity, simultaneous recognition and in-situ detection ( Xu et al., 2017 ; Park et al., 2018 ; Zhang et al., 2018 ; Chen et al., 2019a ; Zhao et al., 2021 ; Slenders et al., 2021 ; Huang et al., 2021b ; Nakamitsu et al., 2021 ). Multianalyte sensors were originally designed for multiple metal ions ( Magri et al., 2006 ), but these systems have subsequently been developed for multiple bioactive molecules ( Yin et al., 2018 ; Zhang et al, 2020b ; Thanzeel et al., 2020 ), bacteria ( Zheng et al., 2018 ), etc.…”

Stress memory for the visualization detection of complicated mechanical structures via trap structure manipulation

“…1 Stressresponsive technology, based on mechanoluminescent (ML) materials featuring the transduction from stress to photon emission, provides a feasible approach for force detection. 2,3 Classified into fractoluminescence, triboluminescence, and elastic luminescence according to the applied mechanical stimulus and the induced response, 4 it allows for the monitoring of structural damage, 5 the recording of frictional contact force, [6][7][8][9] and the imaging of stress distribution. 10 Since the stress distribution of a metal material can be directly displayed by coating the surface of test objects with an upgraded strong ML film of SrAl 2 O 4 :Eu, 11 emerging applications from stress sensors to encrypted anti-counterfeiting, [12][13][14][15] photonic skin, 16 energy harvesting, 17,18 novel light sources 19 and displays have been explored in various frontier domains.…”

2D Van der Waals Rare Earth Material Based Ratiometric Luminescence Thermography Integrated on Micro–Nano Devices Vertically

“…[18,19] Besides, 2D vdW RE materials have excellent luminescence properties especially for the extremely narrow and multiple emissions spanning ultraviolet, visible, and infrared regions, which are ideal for probing temperature. [20,21] Luminescent thermometers can be achieved by monitoring the single emission, luminescence lifetime, and polarization. [4,22] However, single emissionbased luminescent thermometers will be badly affected by local fluctuation such as the concentra tion, size, and geometry of luminescent materials.…”
