Wave length shifting compositions for white emitting diode systems

Special high performance wavelength shifting compositions has been discovered and devised. Further, these compositions when properly distributed in a bulk medium having cooperative properties forms new media having totally unique and useful characteristics. In particular, a special phosphor is devised having a dual peak spectral output when stimulated with high energy photonic input. A dual activator formula is created such that simple manipulation of specified ratios permits flexibility in tuning of color temperature output of the phosphor emitter combination. When prepared with preferred particle sizes and densities, performance improvements are observed. Finally, these phosphors are combined with other special binder materials to form colloid media with well designed optical interaction cross section whereby light emitted from a high intensity blue diode semiconductor will experience just enough wavelength shift in precisely the desired portions of the spectrum, with high efficiency, to form a white LED not found in other systems.
