The conversion and manipulation of light via luminescent down-shifting (LDS) show promise in numerous applications. An elegant combination of lanthanide-doped polymer-derived ceramics incorporated with versatile nanopatterns is demonstrated using direct nanoimprint techniques. The prompt formation of nanoscale photonic structures enhances the fluorescence emission from the LDS while retaining the material’s optical transparency. The functionality of this material is further expanded to accommodate surface energy modulation by nanopatterns. The practical applicability of this platform in photovoltaic devices is evaluated, showing distinctively enhanced efficiency and lifetime mainly attributed to the nanopattern assisted strong LDS property. Moreover, to efficiently combine two lanthanide emissions, so called a “double imprint” approach is devised by superpositioning two LDS nanopatterned arrays (Figure 1). Combined with the multi-functionality such as prominent LDS characteristics, color tunability, and surface energy modulation, the developed LDS platform offers promise for esthetic building-integrated photovoltaics.

Figure 1. Demonstration of an LDS window. The LDS window was visibly transparent under the ambient condition, whereas a beautiful flower emerged under UV excitation. The red flower was formed using Eu, highlighted by the nanocylinders in the middle areas. The green leaves were formed using Tb also with appropriate nanocylinders. The center of the sample displayed the double print technique, which mixed and enhanced the red and green fluorescence to achieve a yellow core.
