This research is to study several variables on the photoluminescence extraction from scales of sea bass such as time, temperature, type of solvents, and ratio between the amount of solvent and the scales. The objective is to obtain the large amount and the best quality of photoluminescence from extraction. This research uses the value of photoluminescence as the indicator to determine its quality for the objective of production in the industrial level. Regarding to the solvent, this research focuses on 4 types of solvent which are Methanol, Chloroform, THF, and DMF. The amount of photoluminescence extract will be compared by using the variable of time for extraction 1 day, 1.5 days, 2 days, and 7 days. Moreover, it will also be compared by using the variable of the temperature between the room temperature and the temperatures of 60-70 ℃. Additionally, the amount of photoluminescence from extraction will be compared in term of variable of ratio between the amount of dissolution and the scales - 1:5, 1:10, 1:20, 1:30. From the experiment, it is found that 4 variables have an impact on the amount of photoluminescence extraction. From comparison, it is discovered that time (1.5 days), ratio between the amount of solvent and the scales (1:20), and temperature (the boiling point of solvent) is the best condition for extraction.
