“…The simultaneous triggering of several ESWs is interesting to enhance reliability and detection accuracy in measurements but also for the possibility of sensing multiple analytes with the same device [26]. In addition, superluminal ESWs can exist [16,27], which is attractive for the excitation of Čerenkov radiation [28][29][30][31].…”

The existence and characteristics of electromagnetic surface waves (ESWs) whose propagation is guided by the planar interface of metal and a tightly interlaced matched ambidextrous bilayer (TIMAB) are theoretically investigated, a TIMAB being a periodic unidirectionally nonhomogeneous material whose unit cell consists of one period each of two structurally chiral materials that are identical except in structural handedness. Thus, the structural handedness flips in the center of the unit cell. A canonical boundary-value problem was formulated and a dispersion equation was solved, the ESWs being classified as surface-plasmon-polariton (SPP) waves. Flipping the structural handedness once in the unit cell can greatly enhance the number of possible SPP waves, one or more of which may be superluminal.

A series of tungstate double perovskite Ca3WO6 doped with Tb3+ was prepared by a combustion process using urea as a flux. The crystal structure identification of Ca3WO6:Tb3+ phosphors was done using X‐ray diffraction patterns, and a monoclinic structure was discovered. The Fourier transform infrared spectrum of Ca3WO6:Tb3+ displayed characteristic vibrations of tungstate bonds. Under 278 nm excitation, Ca3WO6:Tb3+ exhibited intense downconversion green emission, which corresponded to the 5D4–7FJ (J = 4,5) transitions of Tb3+. The phosphor exhibited the highest photoluminescence (PL) intensity when it was doped with 1 mol% of Tb3+; later intensity quenching appeared to be due to the multipolar interaction at higher dopant concentrations. Moreover, high‐quality thermoluminescence (TL) was detected when phosphors were irradiated using beta rays. The effects of Tb3+ concentration and beta dose on TL intensity were the two major aspects studied in detail. The TL intensity demonstrated excellent linear response to the applied range of beta dose. The trap parameters of the studied phosphors were computed by the peak shape approach and glow curve deconvolution. The fading effect on TL intensity was studied by recording the TL glow curves after 1 month of beta irradiation. Obtained results from the PL and TL characterizations showed that the phosphors under study have the potential to be used in lighting displays and in thermoluminescence dosimetry.
