Achieving multicolor emission is a fascinating goal that remains challenging for zero-dimensional (0D) hybrid halides. We successfully obtained a three-millimeter-scale 0D (MXDA)CdBr (MXDA = CHN) single crystal (SC) by the solvothermal method. It serves as an outstanding host for doping with various valence activators, such as Cu, Mn and Sb, and these doped single crystals emit blue (470 nm), yellow (580 nm) and red (618 nm) fluorescence, which accurately cover a large visible region and achieve efficient multicolor emission.

On the heels of the continuous development of optical fiber sensing technology, optical fiber sensors based on surface plasmon resonance (SPR) have attracted widespread attention. Herein, an SPR sensor based on the six nested anti-resonant fiber (ARF) is designed and analyzed by the finite element method (FEM). All the structural parameters are optimized to achieve high-sensitivity liquid refractive index detection.

In this study, a sensitive diagnosis and spontaneously photocatalytic therapy of cancer based on chemiluminescence (CL) and nanozyme was studied. Briefly, carbon nitride-supported copper nanoparticles (CuCNs) loaded with luminol (CuCN-L) were utilized to develop a microneedle patch (CuCN-L/MN). The CuCN-L probe could target overexpressed HO in the TME and actively emit CL to achieve cancer cell imaging for diagnosis.

Objectives: In recent years, significant progress has been made in the research of gesture recognition using surface electromyography (sEMG) signals based on machine learning and deep learning techniques. The main motivation for sEMG gesture recognition research is to provide more natural, convenient, and personalized human-computer interaction, which makes research in this field have considerable application prospects in rehabilitation technology. However, the existing gesture recognition algorithms still need to be further improved in terms of global feature capture, model computational complexity, and generalizability.

Infrared (IR) photodetectors play an important role in many fields such as industry, medicine, security, Achieving high response and maintaining stability in the device performance while reducing materials cost are required for the practical use of optical sensors. This study presents the development of a low-cost but high-performance IR photodetector based on a hybridization of up-conversion microparticles of NaYF:Tm,Yb (UCMPs) and reduced graphene oxide material (RGO). In this combination, UCMPs play the role of absorbing photons from 980 nm excitation light, generating electron-hole pairs, which are useful for sensing applications.
