In this paper, we present a technological method for creating high-density luminescent structures based on up-conversion NaYF4:Yb3+, Er3+ particles and experimentally demonstrate the possibility of their creation. This technology is applicable for large-scale fabrication of patterned media with a level of filling with microparticles of more than 96% for the fabrication of planar structures applicable in photonics and optoelectronics.
