Abstract
Holmium doped lithium niobate (LN:Ho) powders with initial concentration of holmium in the range 0–7 mol% were synthesized by the ceramic powder processing method. Niobium penta-oxide Nb 2O 5, lithium carboxide LiCO 3 and holmium oxide Ho 2O 3 with a purity of 99.99% were the starting materials. The phase content and lattice parameters of powders and ceramic pellets were characterized by X-ray diffraction (XRD). To further investigate the quality of the synthesized LN:Ho powders, the scanning electron microscopy (SEM) was used to determine the particle size and the morphology. The main results of this work point out the fact that the ceramic powder processing method is a well adapt method for obtaining high quality LN:Ho ceramics in the holmium concentration range analysed as the LiNbO 3 phase is lonely present in the ceramics at the end of the synthesized process and as their grain sizes are regular, with a maximum for the sample doped with 7 mol% of holmium.
