2D OLED Array Using High Upconversion Efficiency Nanoparticles for Directly Converting IR to Visible Light

Based on recent advancement in high upconversion efficiency rare-earth-element (REE) nanoparticles and their application in organic polymer LEDs (OLED), IPITEK, teamed with Prof. Andrew Steckl of the University of Cincinnati, proposes a novel two-dimensional OLED Array (2D-OLEDA) to address dual use infrared (IR) sensing and detection needs. The 2D-OLEDA represents a new generation IR detection system, incorporating novel REE-nanoparticles with high upconversion efficiency into OLED device structures. The proposed 2D-OLEDA system will combine many attractive new features: a) ultra-compact and light weight compatible with a goggle-type lenspiece in less than 50 grams; b) low-power consumption; c) highly transmissive at visible wavelengths; and d) cost-effective. Phase I will address feasibility and assess detection sensitivity, selectivity, spatial, temporal and radiometric resolution, visible spectrum transmissivity, and fabrication technology. Phase II will develop the materials and methods to demonstrate a proof of concept lenspiece.
