Development of Blue/Green Emitters Utilizing Homoepitaxial ZnSe-Based Heterostructures

Eagle-Picher Research Laboratories
Miami, OK

Eagle-Picher Research Laboratories, Miami, OK, received an NIST Advanced Technology Program (ATP) award in 1992 to pursue a promising new approach for making highly controlled semiconductor crystals that emit green or blue wavelengths of light for long-lasting, true-green, light-emitting diodes (LEDs). As a result of ATP funding, Eagle-Picher and its research partner, North Carolina State University, have successfully developed a method to routinely fabricate functional blue and green encapsulated LEDs. Several new products have come about as a result of this program which are useful for TV or computer displays because they complete the color spectrum. An even more significant application of green/blue LEDs is optical storage because of their potential for packing more information into optical storage systems than is possible with existing red-light devices.
