The μ-pulling down technique has permitted to grow single crystal fibers, of the gross chemical formula K3Sr2NdNb10O30, having a sufficient optical quality to carry out spectroscopic studies. The crystal structure has been determined and refined to

We present characterization of the hyperfine and quadrupole interactions of praseodymium in La 2 ( WO 4 ) 3 . The hyperfine structure of the H 4 3 ( 0 ) → 1 D 2 ( 0 ) transition is calculated from a crystal-field analysis and is compared to experim

Single Crystals of the series K3Sr2LnNb10O30 (Ln = Lanthanide) have been grown by two different techniques: micro-pulling down and solid state growth. The cationic distribution within the three large cavities of the lattice, determined from the cryst

Effects of the high pressure on the emission spectra of Eu3+-activated L-EuBO3 were considered at room temperature up to 100 kbar. The position of five 0–2 lines in the 5D0→7F2 transition region was determined. The pressure does not have the same
