Abstract:
An optical spectrometer may include an optical filter including a plurality of filter layers formed on a base substrate. The filter layers may include a perovskite material and at least two filter layers among the plurality of filter layers may include perovskite materials having different composition ratios from each other. The filter layers may show respective band-gap characteristics in different optical wavelength ranges from each other, in an optical absorption spectrum and/or an optical transmission spectrum.
