A groundbreaking advancement in room-temperature phosphorescence (RTP) materials has been achieved by the research team at the School of Physics, Xi'an Jiaotong University. The team has successfully developed a scalable method for producing monodisperse RTP SiO₂ nanospheres (RTP-SiO₂ NPs) with a single-batch yield exceeding 700 grams. These unique nanospheres exhibit remarkable self-assembly capabilities, forming photonic crystal structures that display a multimodal luminescent profile encompassing structural color, fluorescence (FL), and RTP. Moreover, the research team ingeniously utilized the angular dependence of the photonic bandgap (PBG) to manipulate the light propagation path within RTP photonic crystal gels, thereby boosting the efficiency of photon-matter interactions. Concurrently, by finely tuning the refractive index matching between SiO₂ and the liquid matrix via temperature, the team achieved dynamic light scattering control, significantly amplifying the luminescent intensity of the gels. This notable accomplishment, titled "Scalable Synthesis of Phosphorescent SiO₂ Nanospheres and Their Application in Angle-Dependent and Thermoresponsive Photonic Gels with Multimodal Luminescence," was published in Nature Communications, heralding new horizons for the development of advanced multimodal luminescent devices.
