WitrynaIn this paper we present the results of ab initio calculations of charge-transfer absorption bands in Eu3+ and Yb3+-doped CaF2 and SrF2 crystals, which are due to transitions from the top of valence band to 4f state of trivalent rare-earth ion. The density-functional theory calculations have been … WitrynaThis document provides guidance on the content and qualification of impurities in new drug substances for registration applications. It applies to drug substances produced by chemical syntheses and not previously registered in a region or Member State. It covers chemistry and safety aspects of impurities in new drug substances.
WitrynaWe have measured the heat capacity and magnetic susceptibility of Yb 1- x Lu x B 12 single crystals in the temperature range from 4 to 300 K. For x⩽1/2, formation of an energy gap is manifested by a strong decrease in the magnetic susceptibility below 100 K. The heat capacity exhibits a Schottky anomaly with an activation energy of about … WitrynaThe spectroscopic characterization of ytterbium-doped LiYF4 (Yb:YLF) is revisited and the prerequisite crystal purity to achieve laser cooling below liquid nitrogen temperatures is shown. 8 PDF Understanding and Preventing Photoluminescence Quenching to Achieve Unity Photoluminescence Quantum Yield in Yb:YLF Nanocrystals
