The chemical
structure of DRCs, SMSED, and the modified SiO2 was characterized
by the KBr pellet method using a Thermo Nicolet NEXUS FTIR spectrometer
(V70, BRUKER OPTICS, Germany). The phase analysis of DRCs and SMSED
was performed using an X-ray diffractometer (XRD-6100, SHIMADZU, Japan).
The fluorescence spectra and afterglow decay curves of SMSED were
measured using a fluorescence spectrophotometer (Omni-λ300i,
ZOLIX, China) equipped with an afterglow tester (PR305, SENSING, China).
The surface morphology of DRCs and SMSED was analyzed through a field
emission scanning electron microscope (Quanta 650 FEG, FEI, Czech
Republic) after Au coating.

Multimodal Characterization of Piezoelectric Ceramics

Check if the same lab product or an alternative is used in the 5 most similar protocols
Powder XRD patterns of the as‐synthesized SAOCD were carried out on an XRD‐6100 (Shimadzu. Japan) X‐ray diffractometer with CuKα radiation (λ = 1.54178 Å). The morphology and element distribution of the samples were obtained by SEM (FEI Quanta 650 FEG) with energy dispersive X‐ray spectroscope fittings (EDAX ELEMENT). The TL curves were measured using a microcomputer thermoluminescence spectrometer (FJ427A1, Beijing Nuclear Instrument Factory) at a heating rate of 1 Κ s−1. ML signals were collected in situ from a homemade tensile testing machine using a high‐throughput optical fiber. The ML spectra were recorded by a fluorescence spectrophotometer (Omni‐λ300i, Zolix Instruments Co., Ltd.) equipped with a CCD camera (iVac‐316, Edmund Optics Ltd.). The stress‐strain curve of SAOCD/PDMS elastomer was applied by a universal testing machine (Shimadzu AGS‐X‐500 N). The triboelectric potential was collected by using the electrostatic measuring probe (SK050, KEYENCE (Japan) Co., Ltd.) at a distance of 10 mm. The CL spectrum of SAOCD was detected on the modified Mp‐Micro‐S instrument attached to the SEM. High‐temperature environments were provided by the heating table (JF‐956A). All optical photos were taken by a digital camera (Canon EOS 77D).

Characterization of Y2O3:Er3+/Tm3+ UCNPs

Check if the same lab product or an alternative is used in the 5 most similar protocols
The crystallographic features of the as-prepared UCNPs were examined by an X-ray diffractometer (XRD) with Cu K radiation at 40 kV and 40 mA (Bruke D8 Advance, Hangzhou, China). The morphology and size of the Y2O3:Er3+/Tm3+ UCNPs were characterized by transmission electron microscopy (TEM; Tecnai G2 F20, FEI, Changsha, China). The compositional elements of the UCNPs were measured by an energy dispersive spectrometer (EDS). For photoluminescence experiments, the 808 and 980 nm fiber coupled diode lasers (BWT K808DAHFN-25.00W, BWT K976DA3RN-30.00W, Changsha, China) were used as the excitation sources. Additionally, the generated UCL was collected and detected by a monochromator (Zolix Omni-λ300i, Changsha, China) and a photomultiplier (PMT). The photos of the UCL color were taken by a Complementary Metal Oxide Semiconductor (CMOS) sensor (Sony IMX519, Changsha, China). All the above photoluminescence measurements were performed at room temperature, and the test samples were prepared by dissolving the UCNPs in ethanol solution with a mass concentration of 0.5 mg mL−1.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
