<p style="text-align: justify;"><span style="color: black; font-family: Calibri; font-size: 12pt;">Here, we present research focusing on the green light emission using Barium chloride dihydrate (BaCl</span><sub style="color: black; font-family: Calibri; font-size: 8pt;">2</sub><span style="color: black; font-family: Calibri; font-size: 12pt;">.2H</span><sub style="color: black; font-family: Calibri; font-size: 8pt;">2</sub><span style="color: black; font-family: Calibri; font-size: 12pt;">O) as an emitter contrary to commonly used Ba(NO</span><sub style="color: black; font-family: Calibri; font-size: 8pt;">3</sub><span style="color: black; font-family: Calibri; font-size: 12pt;">)</span><sub style="color: black; font-family: Calibri; font-size: 8pt;">2</sub><span style="color: black; font-family: Calibri; font-size: 12pt;">, Ba(ClO</span><sub style="color: black; font-family: Calibri; font-size: 8pt;">3</sub><span style="color: black; font-family: Calibri; font-size: 12pt;">)</span><sub style="color: black; font-family: Calibri; font-size: 8pt;">2</sub><span style="color: black; font-family: Calibri; font-size: 12pt;">, BaCO</span><span style="color: black; font-family: Calibri; font-size: 8pt;">3</span><span style="color: black; font-family: Calibri; font-size: 12pt;">, etc. For this work, different compositions containing BaCl</span><sub style="color: black; font-family: Calibri; font-size: 8pt;">2</sub><span style="color: black; font-family: Calibri; font-size: 12pt;">.2H</span><sub style="color: black; font-family: Calibri; font-size: 8pt;">2</sub><span style="color: black; font-family: Calibri; font-size: 12pt;">O and other components acting as oxidant, fuel, etc. were made and analyzed using TGA and burning tests. The flame intensity was captured using a photocell attached with a green color filter. It was observed that the decomposition behavior and the flame intensity were strongly influenced by the ratio of barium chloride to the oxidizer and by the particle size of the pyrotechnic composition powder. Compositions having a higher amount of oxidizer were found to decompose faster and have a more intense flame color.</span>
