MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611114865 A) filed by Chandigarh University on September 25, 2026, for Phytochemical-Mediated Synthesis Of Silver Nanoparticles Using Terminalia Arjuna Bark For Blue Emission Devices.
Inventors include Shivani Singla; and Radhika.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention relates to phytochemical-mediated synthesis of silver nanoparticles (AgNPs) using Terminalia arjuna bark extract. The bark extract served as a dual reducing 5 and stabilizing agent, enabling rapid, eco-friendly synthesis. UV–Vis spectroscopy revealed a sharp surface plasmon resonance band at 430 nm, while XRD and TEM confirmed crystalline, spherical nanoparticles with an average size of 7–10 nm. FTIR analysis indicated hydroxyl, carbonyl, and amide groups as key functional groups responsible for reduction and stabilization. DLS and zeta potential measurements 10 demonstrated moderate colloidal stability. Photoluminescence studies showed an intense blue–violet emission centered at ~425 nm with high color purity (95.9%), highlighting the nanoparticles’ suitability for blue emission devices. This work establishes Terminalia arjuna as a sustainable bioresource for producing highly crystalline and photoluminescent AgNPs, advancing their applications in optoelectronics, sensing, and next-generation 15 photonic technologies.
