(a) Wavelength-integrated emission intensities in the range of 385–500 nm as a function of the excitation angle, fixing the emission angle at 15° along ΓM orientation. (b) Angle-dependent wavelength-integrated emission spectra in the range of 420–440 nm for the structured sample in the ΓM and ΓX orientations and the reference sample. (c) The enhancement ratio of the structured sample relative to the reference sample.
