MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202421094993 A) filed by Indian Institute Of Science Education And Research, Bhopal, Madhya Pradesh, on Dec. 3, 2024, for 'large stokes shift material system for spectroscopic investigation.'
Inventor(s) include Ankit Sharma; and Dr. K. V. Adarsh.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention provides a biocompatible, non-toxic material system based on spinel MnCo2O4 microrods capable of producing large Stokes shifts for spectroscopic and imaging applications. The microrods exhibit strong Jahn-Teller distortion resulting in split high-spin and low-spin electronic states, with absorption bands at approximately 487 nm and 770 nm and corresponding emission bands at approximately 621 nm and 815 nm, generating a Stokes shift of about 143 nm. The material demonstrates strong electron-phonon coupling (25 2 meV), fast recombination, and efficient room-temperature emission. The invention further provides a method for using the material system in fluorescence spectroscopy, multispectral imaging, and biomedical or food diagnostics. The large Stokes shift enhances imaging clarity by minimizing excitation-emission overlap and reducing background scattering. The material provides an eco-friendly alternative to hazardous organic dyes."
