Figures

Image of FIG. 1.
FIG. 1.

A schematic cross section of GaN-based LED with a GRIN structure.

Image of FIG. 2.
FIG. 2.

Optical refractive index and transmittance of the films prepared by PECVD at deposition temperatures of 25 and . The inset figure shows the measured structure of the freestanding films.

Image of FIG. 3.
FIG. 3.

Hydrophilicity of the films deposited at 25 and as a function of an external UV light irradiation time. The inset figures show the associated FTIR spectra and the surface morphology of the -deposited film.

Image of FIG. 4.
FIG. 4.

Luminance intensity of the GaN-based LEDs with and without a GRIN structure. The inset figures show the associated electroluminescence spectra and the schematic light extraction from the GaN-based LED with porous layer.

Tables
