  • Figure 1. Top view pictures of the SnCl2 powder and glass slides arrangements. (a) The SnCl2 powder (white color) arranged in a circular form with a diameter of 1 cm, and (b) the glass slides arrangements with the sandwiched SnCl2 in the middle and two other glass slides on its the left and right sides
  • Figure 2. The SnCl2 powder is sandwiched between two glass slides
  • Figure 3. The SnO2 layers produced by direct heating of the SnCl2 powder. Three pairs of SnO2 layers on glass slides are produced. The first, second, and third pairs (from left to right) are produced by 5, 10, and 15 minutes of heating, respectively. The first and second layers of each pair are on the glass slides located on the right and left of the SnCl2 powder, respectively
