Abstract For achieving well-performing optical thermometry, a new type of dual-mode thermometer is explored based on the valley-to-peak ratio (VPR) and fluorescence lifetime Eu 3+ emissions in ZrO 2 :Eu nanocrystals with sizes down to 10 nm. In VPR strategy, intensity between valley (600 nm) generated by emission band overlap 606 nm peak ( 5 D 0 → 7 F ), which highly temperature sensitive, employed, giving maximum relative sensing sensitivity S r ) 1.8% K −1 at 293 good anti-interference...
In this article, a 1.7-2.6-GHz broadband power amplifier (PA) was proposed using the generalized quasi-Chebyshev lowpass matching approach, which directly composed of step-impedance transmission lines (SITLs). First, complete design theory for introduced network provided with detailed equations. The impedance SITLs can be calculated based on specified bandwidth, maximum allowable return loss, and impedance-transforming ratio. electrical length utilized to adjust harmonic impedances perform...
The development of mobile 5G technology poses new challenges for high-frequency and high-performance filters. However, current commercial acoustic wave filters mainly focus on 4G LTE, which operates below 3 GHz. It is necessary to accelerate research A high-selectivity film bulk resonator (FBAR) filter chip the 3.4–3.6 GHz range was designed fabricated in this paper. design procedure includes FBAR parameter fitting, schematic analysis, generation principle transmission zeros (TZs). measured...
A hybrid wideband filter composed of two sections with sharp frequency selectivity is proposed in this article. The first section consists a coupled line (CL), transmission lines (TL), and film bulk acoustic resonator (FBAR) lower frequency. This mainly controls the roll-off. other CLs FBARs higher frequencies. roll-off upper band. insertion loss rejection outside passband are well controlled because CLs. analysis realized by combining microwave network theory modified Mason model for FBAR....
To achieve high-temperature-sensing sensitivity, a new strategy of optical thermometry is designed based on the synergetic luminescence radiative emission lanthanide (Ln) ions and defect-related in ZrO2:Gd3+ nanoparticles. By X-ray diffraction, Raman spectroscopy, electron paramagnetic resonance photoelectron diffuse reflectance temperature-dependent photoluminescence (PL) decay time measurements, thermoluminescence study, we investigate defect nature, relationship between Gd3+ centers, PL...

The BPF composed of three coupled lines (CLs), six matching transmission (TLs) two film bulk acoustic resonator (FBAR) networks ladder-type structure. These FBAR can help greatly enhance the upper lower sideband roll-off BPF. At same time, passband compensated by CLs TLs. odd-even mode theory used to analyze obtain analytical solutions. Through electromagnetic-acoustic...
