“…Li et al . reported the oxidation of PVP bonded with Ag starts from 250 °C and ended at ~400 °C, which is similar to our TG data41. Therefore, we reasoned that the first exothermic peak at ~327.3 °C is due to the decomposition of PVP in hydrothermal precursors.…”

Rare earth doped mid-infrared (MIR) fluorescent sources have been widely investigated due to their various potential applications in the fields of communication, chemical detecting, medical surgery and so forth. However, with emission wavelength extended to MIR, multiphonon relaxation process that strongly quenched the MIR emission is one of the greatest challenges for such practical applications. In our design, we have described a controllable gas-aided annealing strategy to modulate the phase, crystal size, morphology and fluorescent performance of a material simultaneously. Uniform and monodispersed Er3+-doped La2O2S and La2O2SO4 nanocrystals with a similar lattice structure, crystallinity, diameter and morphology have been introduced to investigate the impact of multiphonon relaxation on luminescence performance. Detailed spectroscopic evolutions in the region of MIR, near-infrared (NIR), visible upconversion (UC) and their corresponding decay times provide insight investigation into the fluorescent mechanism caused by multiphonon relaxation. A possible energy transfer model has also been established. Our results present direct observation and mechanistic investigation of fluorescent evolution in multiphonon relaxation process, which is conductive to design MIR fluorescent materials in the future. To the best of our knowledge, it is the first investigation on MIR fluorescent performance of La2O2S nanocrystals, which may find various applications in many photoelectronic fields.

“…This result produced two consequences. Firstly, the PVP present at the interfaces between Ag NPs and PI can serve as a binder to provide robust bonding between the silver membrane and the substrate [20]. Secondly, however, the thin PVP that presented at the interfaces between Ag NPs can restrain the sintering of Ag NPs.…”

Laser-direct writing has become an alternative method to fabricate flexible electronics, whereas the resistive nature of laser-scribed conductors may distort the radio-frequency characteristics of circuits for high-frequency applications. We demonstrate that the transmission characteristics of microstrip lines are insensitive to the resistance of laser-scripted conductors when the sheet resistance is not above 0.32 Ω/ . On the other hand, the transmission and reflection characteristics of the MS lines can be simply modified through the accommodation of the resistance of the conductors, because a laser can trigger the sintering and melting of laser produced silver nanostructures. This could provide an alternative way to fabricate radio frequency (RF) resistors and promote their applications to flexible radio-frequency devices and systems.

Comparing to the defect of weakness impact resistance of epoxy resin based electrical conductive adhesives (ECAs), flexible conductive adhesives (FCAs) could be used in flexible device electronic packaging. Carbon nanotubes (CNTs) have good properties, which make them to be ideal fillers. In this study, CNTs were used as one-dimensional conductive scaffolds to construct effective networks among the TPU polymer in ECAs. The electrical conductivity and tensile strength improved with the CNT content increased from 0 to 10.0 wt%. In addition, the resistance only changed a little within a certain strain. Under the same strain, the change of R/R0 for the samples with high CNT content is smaller than that of the samples with low CNT content after first cycle. The development of highly conductive, flexible, and low cost ECAs will allow them to be widely used in flexible electronic devices packaging in the future.
