Optical Chemosensors Synthesis and Appplication for Trace Level Metal Ions Detection in Aqueous Media: A Review

Study on defects during Fe3+ doping and annealing in ADP crystals

“…Inorganic crystals such as potassium dihydrogen phosphate (KH 2 PO 4 , KDP), ammonium dihydrogen phosphate (NH 4 H 2 PO 4 , ADP), and barium borate (BaB 2 O 4 , BBO) are extensively applied in the fields of frequency converters, monochromators, optoelectronic switches, and optical storage devices due to their outstanding nonlinear optical properties. [1][2][3][4] In high-power laser systems, KDP is currently the only nonlinear optical crystal in practical use. 5 ADP crystals, which share a similar structure with KDP, exhibit superior optical uniformity, enhanced SHG coefficients, improved thermal stability, and higher laserinduced damage thresholds (LIDTs).…”
