Technical Details & Test Data

LEDs (Organic, Polymer, Phosphorescent): They are utilized to modify a variety of surfaces that include glass, metal oxides, plastics and nano-crystals. Plastic substrates are critical in the manufacture of flexible electronic displays. Gelest offers a multitude of materials for metallization via low temperature vapor deposition techniques such as CVD and ALD to yield conductive coatings and dielectric coatings for light emitting diodes to include OLEDs, PLEDs and Phosphorescent OLEDs. The ability to customize the refractive index of Group IV materials makes them ideal candidates for cladding fiber optic cables and planar wave guides. Gelest offers an extensive range of materials for antireflective and refractive index coatings.
