Method of the synthesis and control of pgo spin-coating precursor solutions |
| abstract |
The method for synthesizing the PGO spin coating precursor solution is lead acetate trihydrate (Pb (OAc) 2 · 3H 2 O) and germanium alkoxide (Ge (OR) 4 (R = C 2 H 5 and CH (CH 3 ) 2 ). The use of a starting material). The organic solvent is di (ethylene glycol) ethyl ether. The mixed solution of lead and di (ethylene glycol) ethyl ether is heated in the atmosphere at 190 ° C. or lower for a time at a temperature of 185 ° C. or lower, preferably in the range of 30 minutes to 4 hours. The color of the solution is observed in the heating step to determine when the reaction is complete and when the composition of the desired product begins to form. The solution is then added to germanium di (ethylene glycol) ethyl ether to form a PGO spin coating solution. This second step also requires heating the solution at a temperature below 190 ° C. for a time in the 0.5 to 2.0 hour range. The process yields a PGO precursor solution suitable for use in spin coating. |
