For example, the first emission layer 124 be configured to emit a first excitation emission configured to a first absorption region of the first photoluminescent material 129 that in the combined photoluminescent layer 130 is integrated, to aim. In this way, the first excitation may be configured to be a first photoluminescent material 129 to stimulate.
  • The second emission layer 126 may be configured to emit a second excitation emission configured to include a second absorption region of the second photoluminescent material 132 that in the combined photoluminescent layer 130 is integrated, to aim. The second absorption region may correspond to a substantially different range of light wavelengths than the first absorption region. In this way, the second excitation emission may be configured to be substantially independent of the first photoluminescent material 129 a second photoluminescent material 132 to stimulate. In this configuration, each of the first emission layer 124 as well as the second emission layer 126 configured to be substantially independent of each other the first photoluminescent material 129 and the second photoluminescent material 132 to activate.

In response to the excitation, the photoluminescent member emits emission having at least one wavelength of light at least partially outside the absorption range. In various implementations, the absorption range of the photoluminescent materials may vary, as discussed herein. Additionally, the light emission in the form of emitted fluorescence may be selected based on the material properties of the photoluminescent structures discussed herein.

For example, the first photoluminescent material may comprise a photoluminescent structure of rylenes, xanthenes, porphyrins, phthalocyanines, or other materials suitable for a particular Stokes shift defined by an absorption range and emission fluorescence. The first photoluminescent material 129 can be selected to have a smaller Stokes shift than the second photoluminescent material 132 having. In this way, any of the photoluminescent materials 129 and 132 independently of each other from the first emission layer 124 and the second emission layer 126 be lit to output different light colors.
  • The second photoluminescent material 132 may include a photoluminescent structure configured to produce a larger Stokes shift than the first photoluminescent material 129 , The second photoluminescent material 132 may comprise an organic or inorganic material configured to have the second absorption area and a desired output wavelength or color.
