· TlIO3

Thallium iodate (TlIO3) is an inorganic ceramic compound composed of thallium and iodate ions, belonging to the family of halide-based ceramics. This material is primarily of research interest for nonlinear optical and electro-optical applications, where its crystal structure enables frequency conversion and modulation of electromagnetic radiation. TlIO3 is notably studied in photonics and precision optical systems, though it remains largely experimental; its practical adoption is limited compared to established alternatives like KDP (potassium dihydrogen phosphate) due to toxicity concerns associated with thallium and more complex synthesis requirements.
