Novel Structure

In the study of functional materials, more attention is the construction of organic–inorganic hybrid materials with structural diversity, fascinating properties, and potential applications in catalysis, molecular adsorption, medicine, electro-conductivity, magnetism and photochemistry. At present, the research work in upconversion emission in rare-earth doping materials has been greatly increased. Yb3+ and Ho3+ upconversion energy transfer is attractive, because Yb3+ and Ho3+ upconversion energy transfer is relatively simple compared to upconversion involving other rare-earth ions. In this paper, a novel holmium complex [Ho (C3 H6O9)] •CH3OH has been synthesized from a hydrothermal reaction and the crystal structure has been determined by means of single-crystal X-ray diffraction. The Ho atom is coordinated by eight O atoms. The molecular is antisymmetric structure by the C2-C2 axis. The molecular structure stabilized by the O-H…O hydrogen-bonding interactions.

Rare Earth Fluorides

There has been considerable interest over the past several years in materials capable of converting infrared radiation to visible light by means of sequential excitation in two or more steps. Several rare-earth trifluorides (LaF3, YF3, GdF3, and LuF3) containing a small amount of other trivalent rare-earth ions (Yb3+ and Er3+, or Ho3+, or Tm3+) have been found to exhibit such phenomenon. The methods of preparation of these rare-earth fluorides in the crystalline solid form generally involve a co-precipitation process and a subsequent solid state reaction at elevated temperatures. This investigation was undertaken to examine the morphological features of both the precipitated and the thermally treated fluoride powders by both transmission and scanning electron microscopy.Rare-earth oxides of stoichiometric composition were dissolved in nitric acid and the mixed rare-earth fluoride was then coprecipitated out as fine granules by the addition of excess hydrofluoric acid. The precipitated rare-earth fluorides were washed with water, separated from the aqueous solution, and oven-dried.
