摘要： Embodiments of the invention include a semiconductor light emitting device capable of emitting first light having a first peak wavelength and a wavelength converting element capable of absorbing the first light and emitting second light having a second peak wavelength. In some embodiments, the structure further includes a metal nanoparticle array configured to pass a majority of light in a first wavelength range and reflect or absorb a majority of light in a second wavelength range. In some embodiments, the structure further includes a filter configured to pass a majority of light in a first wavelength range and reflect or absorb a majority of light in a second wavelength range, wherein the filter is configured such that a wavelength at which a minimum amount of light is passed by the filter shifts no more than 30 nm for light incident on the filter at angles between 0° and 60° relative to a normal to a major surface of the filter.
