FTIR Si-O peak has good correlation with FBAR TempCo performance and can be used to characterize and optimize TempCo material.Q. ZouM. SmallD. LeeF. BiR. SnyderT.L. LamersJ. ChoyR. RubyInternational Conference on Solid-State Sensors, Actuators and Microsystems...
SiO2/LaF3:Eu3+ core-shell structural luminescence particles were prepared by a wet method, and the structure and luminescence properties were characterized. XRD patterns showed that the coated LaF3:Eu3+ layer took a cubic crystal phase. FTIR spectra indicated that the citric acid was modified on...
This means that just about half of the initial iron was avail- able to be oxidized during the first charge, but actually no peaks, even of very low peak current, were observed either in the first or in the subsequent cycles. This could also suggest that Fe3+ in the crystalline structure...
Their OH-stretching FTIR spectrum consists of two main bands at ~3740 and 3715 cm?1. At the transition temperature ( Tc ), these bands merge into one single absorption centred at ~3720 cm?1, and no further change is observed beyond this T . Significant modifications consisting in peak ...
The O-H...O distance of <2.5 Aa in mozartite is one of the shortest hydrogen bonded O...O distances in minerals and leads to a diffuse FTIR absorption peak (stretching mode) polarized parallel to b between 1300 and 1700 cm (super -1) . 展开 ...
the only sample to yield suitable polycrystalline grains was LA5. FTIR measurements performed on a 150 μm polycrystalline aggregate from this sample (Fig.7) show an extensive set of absorption peaks at 3374, 3523, 3532, 3557, 3576, 3599, 3614 and 3641 cm−1. The peak at 3641 cm−1...
采用溶胶-凝胶技术制备了Al~(3+)-Ce~(3+)共掺杂的纳米SiO_2,并对其进行H_2气氛中700～800℃的热处理。采用透射电子显微镜(transmissionelectronmicroscope,TEM)、Fourier红外光谱仪(Fouriertransforminfraredspectroscopy,FTIR)、紫外-可见分光光度计(ultraviolet-visiblespectrophotometry,UV-Vis)及荧光光谱仪观察并测试掺...
FTIR and XPS investigations of a-SiOxNy thin films structure Amorphous silicon oxynitride (a-SiON) thin films with large composition variation were deposited by reactive sputtering. Their structural study was carried out by mean of FTIR and XPS analysis. The IR absorption peak maximum was found to...
Various characterization techniques X-ray Diffraction (XRD), Scanning electron microscopy and Energy dispersive spectroscopy) (SEM&EDX) and Fourier transform infrared spectroscopy (FTIR) were used to evaluate the microstructure and phase assemblage of the reaction products as a function of molar ratios ...
摘要:采用静电自组装方法制备了纳米TiO-/SiO光催化材料。采用巯丙基三甲氧基硅烷偶联剂对SiO,进行干法改性,采用双 氧水/冰醋酸将偶联剂巯基基团氧化为磺酸基基团。在正负电荷的吸引下,带负电荷的Si0,与带正电荷的钛聚合阳离子自发地 组装在一起,经一定温度热处理得到纳米TiO-/SiO光催化材料。采用XRD、FTIR、PL、...
