Intelligent Luminescence for Communication Display and Identification
Abstract
A highly integrated, cross-disciplinary research program was conducted to establish the scientific and technological basis for intelligent luminescent materials, devices and systems. Novel luminescent and optical systems were researched to realize a new intelligence modeling methodology: corticonics. Specific achievements include low threshold organic quantum dot emitters, luminescence modification by 3D photonic crystals, beam steering based on a superlattice photonic crystal, optimization of liquid crystal properties, development of optically transparent n- and p-type wide band gap materials and transparent transistors for display applications. It was demonstrated that emissive and active infiltrated photonic crystals, highly transparent conductive materials and nano-structured materials offer the potential for initiating many new device functions. For example, low-threshold tunable sources and detectors, optically and electronically controlled optical switching, beam steering, and bi-stable elements for logic and threshold computing decisions. Also new family of highly nonlinear liquid crystals that exhibit, hi-stability, self-oscillations and. bifurcation were identified as a promising class of materials for implementing and testing the corticonic paradigm. A novel, transparent, thin-film enhancement-mode transistor was reported with ~ 90% visible transparency and an on/off ratio of 10(to the 6th power) for integration into display and identification systems.
