Abstract Organic–inorganic perovskite crystals (C 6 H 5 C n 2 NH 3 ) PbCl 4 ( = 1: PMA, 2: PEA, 3: PPA, and 4: PBA) were prepared, their scintillation characteristics evaluated. A broad emission peak originating from self-trapped excitons (STE) was observed all of the when excited by 310 nm light. Further, also clearly PBA under X-ray. Moreover, light yields ? -ray calculated to be 1460 (PEA), ...

The interface-induced second-harmonic generation from ferroelectric hafnium–zirconium oxide (Hf0.5Zr0.5O2) epitaxial thin films, buffered with a La0.67Sr0.33MnO3 bottom electrode, is analyzed as function of input and output polarization angles the azimuthal angle sample for several film thicknesses. It shown that signal generated mainly buffer side interface, rather than side. However, affects ...

Abstract. The new mineral batoniite, [Al8(OH)14(H2O)18](SO4)5 ⋅ 5H2O, was discovered in the Cetine di Cotorniano Mine, Chiusdino, Siena, Tuscany, Italy. It occurs as hemispherical aggregates composed of brittle tabular crystals, up to 1 mm size, white colorless color, with a streak and vitreous greasy luster. Batoniite is biaxial negative, α= 1.4833(6), β= 1.4948(6), γ= 1.5019(5) (589 nm), 2V(m...

Abstract. Absorption cross sections of emerging greenhouse gases (GHGs) were measured to estimate the radiative efficiency using high-resolution Fourier transform infrared spectroscopy (HR-FTIR). For quantitative spectroscopy, Beer–Lambert parameters absorber pressure, temperature, and optical path length (OPL) accurately determined be traceable primary standards. The OPL multipass cell mounted...
