- Lanthanum aluminate nanoparticles, sol-gel route, SEM
Abstract
Lanthanum aluminate was synthesised by simple sol-gel route to get a homogenously mixed powder. Hexahydrated Lanthanum Nitrate and Aluminium Nitrate were used as precursors, heat treated to obtain a fine grained powder of Lanthanum Aluminate. The powder was calcined at 800°C to get fine Lanthanum
Aluminate powder and then characterised by XRD, SEM and EDAS to obtain the structure, morphology and composition. The XRD revealed the formation of a crystalline phase of lanthanum aluminate with a rhombohedral structure. The SEM revealed the agglomeration of lanthanum aluminate nanoparticles and
energy dispersive spectrum indicated the existence of O, Si and Al in the sample. The observed results indicated the feasibility of utilizing Lanthanum aluminate nanoparticles to prepare thin film using evaporation technique which could find application as dielectric in thin film transistors.
