“…Numerous studies on TGS crystals doped with xylenol orange, amaranth, sunset yellow, and crystal violet dyes have been reported. [7][8][9][10] Xylenol orange dye had been used to improve the properties of various organic and inorganic crystals, such as ammonium dihydrogen phosphate (ADP), potassium dihydrogen phosphate (KDP), L-alanine, thiourea and benzophenone. [1,[11][12][13][14] During our extensive research review, we discovered that colored crystals have richer specific properties than their host uncolored crystals.…”
