Endowing a single material with various types of luminescence, that is, exhibiting simultaneous optical response to different stimuli, is vital in fields. A photoluminescence (PL)- and mechanoluminescence (ML)-based multifunctional sensing platform built by combining heterojunctioned ZnS/CaZnOS:Mn2+ mechano-photonic materials using 3D-printing technique fiber spinning. ML-active particles are embedded micrometer-sized cellulose fibers for flexible devices capable emitting light driven...
Optically active luminescent materials based on lanthanide ions attract significant attention due to their unique spectroscopic properties, nonlinear optical activity, and the possibility of application as contactless sensors. Lanthanide metal-organic frameworks (Ln-MOFs) that exhibit strong second-harmonic generation (SHG) are optically in NIR region unexpectedly underrepresented. Moreover, such Ln-MOFs require ligands chiral and/or need multistep synthetic procedures. Here, we show pulsed...
Abstract Nonlinear optical materials are essential in areas such as nanophotonics, information processing, and biomedical imaging. However, nanomaterials employed for these diverse applications to date efficient only one type of nonlinear activity. Herein, the first multimodal optically active class based on lanthanide‐doped lithium niobate nanoparticles, which simultaneously exhibit unprecedentedly second third harmonic generation, well up‐conversion photoluminescence, is reported. These...

Chemical compounds with high upconversion (UC) intensity are still needed for temperature-sensing media based on the fluorescence ratio (FIR) technique of UC materials. In this work, citrate-based sol–gel method was used to produce Yb3+/Er3+–Bi3+ codoped Ba2YV3O11 (BYVO) nanophosphors. Using X-ray diffraction, scanning electron microscopy, and transmission we examined influence Bi3+ ions phase structure morphology BYVO examined. Power-dependent photoluminescence (PL) spectroscopy shows how...
Abstract The pursuit of developing novel approaches to fully organic and efficient phosphorescent materials is in high demand. optical activity such functional, phosphorescent/fluorescent may exhibit great temperature dependence, allowing their application as advanced, highly sensitive molecular thermometers. In this study, a rational strategy involving host–guest complexation polymerization [2.2]paracyclophane (PCP) based molecules with cucurbit[8]uril (CB8) suppress the motion promote...
In the last few years, huge progress has been made in development of remote optical thermometry strategies, due to their non-contact, high-sensitivity and fast measurement characteristics, which are especially important for various industrial bio-applications. For these purposes, lanthanide-doped particles seem be most promising luminescence thermometers. this study, Tm3+/Yb3+:Na3GdV2O8 (NGVO) phosphors were prepared using a sol-gel method. Under 980 nm excitation, upconversion (UC)...
We experimentally demonstrate the high sensitivity of a novel liquid state, whispering-gallery-mode optical resonator to humidity changes. The used consists droplet made glycerol, transparent that enables quality factor, doped with fluorescent material. As glycerol is highly hygroscopic, refractive index and radius change ambient humidity. This produces shift on whispering gallery mode's wavelengths, which modulates emission device shows an unpreceded 10-3 per relative percent.
Abstract Glass microspheres embedded with Nd 3+ ‐doped nanoperovskites based on yttrium orthoaluminate are synthesized and used as optical vacuum sensor. Under 532 nm excitation, the show two emission bands centered at 820 890 nm, corresponding to 2 H 9/2 , 4 F 5/2 → I 3/2 transitions. When heated by laser excitation in air (ambient conditions), positions of Stark level transitions shift toward red or blue spectral regions. Additionally, full width half maximum these peaks increases....
