Obtention of good quality Ba2NaNb5O15 crystals: growth characterization and structure of Nd3+-doped single-crystal fibres
- 1. Lyon-1 Univ., 69 - Villeurbanne (France)
Description
The obtention of good quality and crackless Ba2NaNb5O15 (BNN) single crystals doped with different amounts of Nd2O3 is reported. The crystals were grown as monocrystalline fibres by the Laser Heated Pedestal Growth technique (L.H.P.G.). A new determination of the crystallographic structure of BNN has been performed on 1 at % Nd3+ -doped fibres. It was found orthorhombic with the space group Pba2 instead of Cmm2. The well known twinning of BNN disturbing the optical properties and due to the exchange of the a and b axis of the unit cell is shown to decrease as the neodymium content of the increases. Above 3% Nd3+ doping, BNN fibres were found tetragonal. (authors). 22 refs., 8 figs., 3 tabs
