Upconverting nanoparticles (UCNPs) possess a unique ability to convert near-infrared (NIR) light into higher-energy visible light. This characteristic has led extensive investigation in numerous fields, including biomedical imaging, medicine, and optoelectronics. However, the potential toxicity of U

Chemical formulas indicate the building blocks of matter. Grasping these formulas provides a critical basis for exploring the vast world of chemistry. They encode information about the types of atoms present in a material, as well as their relative quantities. A chemical formula can quickly depict
