Single crystals of Holmium (Ho) doped La 3 Ga 5 SiO 14 were grown along c-axis by using the Czochralski method. The structure of the crystal was studied by X-ray powder diffraction (XRPD) and found the crystal structure still belonged to the space group P321. The unitcell parameters were calculated
## Abstract The absorption and fluorescence spectra of Dy^3+^โdoped La~3~Ga~5~SiO~14~ (LGS) crystals were measured and analyzed according to the JuddโOfelt theory. When applied, the following spectral parameters have been obtained: phenomenological intensity parameters __ฮฉ__~__t__~, __ฮฉ__~2~โ=โ2.64
The spectroscopic properties of two partially disordered crystals langasite (LGS) and langatate (LGT) doped with Eu 3+ were investigated. The fluorescence lifetimes of 5 D 0 and 5 D 1 excited levels are measured. The spectroscopic figures of merit R 0 , R 2 (the areas of the electric-dipole transiti
