DOI: 10.1002/adfm.202212037
Abstract: Orthogonal upconversion with color‐switchable emissions under different excitation conditions provides new chances to diverse frontier applications of luminescent materials. However, the previous orthogonal upconversion systems compulsorily require the precise control of spatial distributions of dopants… read more here.
