采用改进的溶胶-凝胶法制备了Sr0.5Ba0.5Nb2O6（SBN 50）薄膜。以醋酸锶、醋酸钡和乙醇铌为原料，乙二醇为络合剂，乙二醇为溶剂，乙二醇为络合剂。发现乙二醇是在用适当选择量的乙酸和2-甲氧基乙醇稀释溶液后增加溶液抗沉淀的长期稳定性和将结晶温度降低至700°C所必需的组分。溶剂的种类、用量和混合顺序对SBN 50薄膜的晶化行为有影响。
Sr 0.5 Ba 0.5 Nb 2 O 6 (SBN50) thin films were prepared by the modified sol-gel process, where the complex solution was spin-coated onto Si(100) or ITO-coated glass substrates and heat-treated at the temperature range of 650∼900°C. Stock solution was synthesized from Sr-acetate, Ba-acetate and Nb-ethoxide using 2-methoxyethanol or acetic acid as solvent and ethylene glycol as complexing agent. It was found that ethylene glycol was the component necessary to increase the long-term stability of the solution against precipitation and to decrease the crystallization temperature to 700°C upon diluting the solution with the properly selected amount of acetic acid and 2-methoxyethanol. The type, amount and mixing order of solvents were proved to influence the crystallization behavior of SBN50 thin films.
