Photonic superlattice-based devices and compositions for use in luminescent imaging, and methods of using the same

A method comprising:

• receiving first luminescence at a first wavelength, the first luminescence received by a first optical component and from a first analyte site in contact with a photonic superlattice, the photonic superlattice supporting propagation of the first wavelength and a second wavelength;
• and
• receiving second luminescence at the second wavelength, the second luminescence received by the first optical component and from a second analyte site in contact with the photonic superlattice, the photonic superlattice inhibiting propagation of a third wavelength between the first and second wavelengths.

A composition comprising:

• a photonic superlattice supporting propagation of a first wavelength and a second wavelength, the photonic superlattice inhibiting propagation of a third wavelength between the first and second wavelengths;
• and
• a first material at a pattern of analyte sites in contact with the photonic superlattice, the first material comprising first and second luminophores, the first luminophore emitting first luminescence at the first wavelength at an angle, the second luminophore emitting second luminescence at the second wavelength at approximately the angle.
