Problems solved by technology

Although structures with strong emissivity and enhanced stability can be obtained by incorporation of highly emissive inorganic cores and strong binding ligands to generate extended 1D, 2D, and 3D networks, serious limitations still exist, such as low blue light Excitement and poor solution processability, the latter being a common problem with most inorganic materials
