The deposition system used in this

The deposition system used in this
work was based on a home-made commercial humidifier with a frequency of 1.2 MHz adapted for
atomization of the starting solution. Sodocalcic glass plates of about 2.5 × 5.0 cm
2
sizes with a thickness
of 1.1 mm, cleaned previously were utilized as substrates. A molten tin bath was used for substrate
heating, and the temperature of the bath was electronically controlled and monitored by a K-type
thermocouple. Substrate temperatures selected were 400, 425 and 450 °C, within ±1 °C variation
