摘要
A luminescent layer includes a series of down-converting luminophores dispersed in a matrix to collect ambient light energy over a range of wavelengths longer than a desired color band and a set of up-converting luminophores dispersed in the matrix. The series of down-converting luminophores transfer the ambient light energy to the set of up-converting luminophores, and the set of up-converting luminophores emits at least a portion of the ambient light energy in the desired color band.
