AI Technical Summary

Technical Problem

Existing barium organic complexes have insufficient volatility during thin film deposition, high preparation costs, and complex processes, making it difficult to meet the requirements of efficient chemical vapor deposition.

Method used

A stable barium complex is formed by a neutral nitrogen heterocyclic chelating ligand with abundant coordination sites and barium ions. The complex is prepared by reacting the barium salt in an aqueous solution, avoiding the use of high-cost metallic barium raw materials. The simplified preparation method includes chelation reaction and recrystallization purification.

Benefits of technology

It significantly improves the volatility of barium complexes and reduces production costs, achieving an efficient and stable chemical vapor deposition process, and lowering the initial volatilization temperature and residual rate.
