Used as a near-infrared (NIR) absorbing dye with strong absorption in the 800–1100 nm region for optical applications, including laser protection, optical limiting devices, and infrared detection systems. Its properties make it suitable for filters, sensors, optical communication, distance detection, and thermal imaging where selective transmission or blocking of specific wavelengths is required. Commonly incorporated into polymer matrices or coatings to develop smart windows, photodetectors, protective eyewear, and advanced photonics such as optical amplifiers and switches. Also explored in photothermal therapy and imaging due to its efficient light-to-heat conversion, with applications in devices utilizing photoconversion to electrical signals. Exhibits good stability in diverse environments.
