An anti-reflection coating has an average total reflectance of less than 10%, for example less than 5.9% such as from 4.9% to 5.9%, over a spectrum of wavelengths of 400-1100 nm and a range of angles of incidence of 0-90 degrees with respect to a surface normal of the anti-reflection coating. An anti-reflection coating has a total reflectance of less than 10%, for example less than 6% such as less than 4%, over an entire spectrum of wavelengths of 400-1600 nm and an entire range of angles of incidence of 0-70 degrees with respect to a surface normal of the anti-reflection coating.

The invention relates to light-emitting devices, and related components, systems and methods. In one aspect, the present invention is related to light emitting diode (LED) light extraction efficiency. A non-limiting example, the application teaches a method for improving light emitting diode (LED) extraction efficiency, by providing a nano-rod light emitting diode; providing quantum wells; and reducing the size of said nano-rod LED laterally in the quantum-well plane (x and y), thereby improving LED extraction efficiency.
