The beamline I23 at Diamond Light Source will be the first dedicated beamline for long-wavelength phasing experiments from macromolecular crystals (MX). The challenges of in-vacuum long-wavelength macromolecular crystallography and the opportunities by extending the wavelength range towards the sulfur and phosphorous K-absorption edges will be discussed and an overview on the current status of the project will be given.

Eu3+ activated Ca3Ga2Ge3O12 ceramics were prepared by solid-state reaction, and characterized with XRD, UV-VIS and UV-VUV spectroscopy at temperature range 10-300K. Structural analysis revealed only garnet phase. The results have shown that Eu3+ activated Ca3Ga2Ge3O12 exhibit efficient red emitting due to the 5D0 → 7F1,2,4 transitions under 393 nm (7F0 → 5L6 transition of Eu3+) or 250 nm (the broad O2-→Eu3+ charge transfer band) excitations. A strong activator emission of Ca3Ga2Ge3O12:Eu3+ ceramics can also be obtained upon excitation with the synchrotron radiation in the long-wavelength fundamental absorption edge region and in the region of photon multiplication, where energy transfer from the host to the Eu3+ ions takes place.

The vitreous samples of MIxNa4-xCoFe(PO4)3 (x = 0, 0.2 and 1.0, MI - Li, K) composition were prepared by melt method. Formation of Nasicon-related crystalline samples was caused by the annealing at 600 °C. The cell parameters calculation showed that its evolution along two series agrees with the substitution of Na+ by smaller Li+ and bigger K+ cations. The electrical properties were investigated by the impedance method.

Positron annihilation lifetime spectroscopy combined with Doppler broadening of annihilation radiation was applied to study free-volume entities in Ge-Ga-S glasses having different amount of CsCl additives. These results serve as a basis for new direction in the characterization of inner free-volume structure of chalcohalide glass-ceramics conditionally declared as Positronics.

The high optical quality glasses with Li2B4O7:Eu, CaB4O7:Eu, and LiCaBO3:Eu compositions containing 0.5 and 1.0 mol. % Eu2O3 have been obtained by standard glass technology. Using electron paramagnetic resonance (EPR) and optical spectroscopy it was shown that the Eu impurity is incorporated into the Li2B4O7, CaB4O7, and LiCaBO3 glasses network as Eu3+ (4f6, 7F0) ions, exclusively. All observed f - f transitions of the Eu3+ centres in optical absorption, luminescence excitation and emission spectra were identified. Luminescence kinetic shows single exponential decay with different lifetimes for Eu3+ centres in the Li2B4O7, CaB4O7, and LiCaBO3 glasses.

For the first time the diagnostics of oxyorthosilicates single crystals based on self-action of picosecond range laser pulses at 1064 nm has been performed. It was found high sensitivity of the photoinduced refractive index variation to the substitution of the Lu atoms by Gd as well as the admixture of Ce to the LSO/LGSO crystalline matrix. The effect could be attributed to the different electron detrapping-recombination processes efficiencies due to the oxygen vacancies excitation.
