Conference proceedings 1981mmemorate the memory of Professor Sergio Porto who died suddenly about one year earlier while attending a laser conference in the Soviet Union. The sub ject matter covered the active areas of laser devices, photochemistry, non linear optics, high-resolution spectroscopy, photokinetics, photobiolog小步走路 发表于 2025-3-27 09:03:13
IR Laser Absorption Spectroscopy of Local Modes of the H- Ion in Pure and Rare-Earth-Doped CaF2dral symmetry. The crystal shows strong IR absorption due to localized modes of the hydride ion. In CaF. crystals doped with trivalent rare-earth ions the H. can serve as a charge compensator for the impurity ions. In this role it replaces the corresponding fluorine ions in interstitial lattice sites .Palate 发表于 2025-3-27 11:09:31

Raman Scattering Study of the Phase Transitions in (NH4)2Cd2(SO4)3h decreases exponentially on lowering the temperature further. The sudden jump in ε(0) is accompanied by a paraelectric-ferroelectric phase transition with the appearance of a constant spontaneous polarization . For these reasons, CAS is known as an improper ferroelectric.anaerobic 发表于 2025-3-27 23:18:20
