1. An improved LED device, comprising:

  • a substrate;

    at least one coating layer applied to a surface of the substrate, the coating layer formed from alternating thin film layers of alumina and silicon carbide, the coating layer configured to reflect at least 95% of a first electromagnetic signal at a first wavelength range and transmit at least 95% of a second electromagnetic signal at a second wavelength range;

    at least one active layer positioned on the substrate and in communication with an energy source configured to emit the first electromagnetic signal within the first wavelength range and at least the second electromagnetic signal within at least the second wavelength range; and

    an encapsulation device positioned to encapsulate the active layer.
