Patent number: 11773282Abstract: The present invention relates generally to using upconverting inks for producing highly-resolved patterns for inter alia, security applications. More specifically, the present invention relates to the use of sols (inks) and printing processes that produce well-defined printed features consisting of polymers impregnated with luminescent upconversion nanocrystals. The patterns printed using such inks and processes may exhibit defined shapes, characters of text, and various other types of images.Type: GrantFiled: July 2, 2019Date of Patent: October 3, 2023Assignee: SOUTH DAKOTA BOARD OF REGENTSInventors: Jon Kellar, P. Stanley May, William Cross, Jeevan Meruga, Tyler Blumenthal

Patent number: 11568161Abstract: An improved system and method for reading an upconversion response from nanoparticle inks is provided. A is adapted to direct a near-infrared excitation wavelength at a readable indicia, resulting in a near-infrared emission wavelength created by the upconverting nanoparticle inks. A short pass filter may filter the near-infrared excitation wavelength. A camera is in operable communication with the short pass filter and receives the near-infrared emission wavelength of the readable indicia. The system may further include an integrated circuit adapted to receive the near-infrared emission wavelength from the camera and generate a corresponding signal. A readable application may be in operable communication with the integrated circuit. The readable application receives the corresponding signal, manipulates the signal, decodes the signal into an output, and displays and/or stores the output.Type: GrantFiled: May 27, 2020Date of Patent: January 31, 2023Assignee: SOUTH DAKOTA BOARD OF REGENTSInventors: David Langerman, Jon Kellar, William Cross, P. Stanley May, Julian Brackins, Jeevan Meruga, Aravind Baride, John Rapp
