Summary: This paper reports a novel method for synthesizing CD-doped SiO(2) MPs with tunable afterglow properties and size distributions. The pseudomorphic transformation of SiO(2) MPs enables CD doping, providing a hydrogen bond-enriched environment for triplet state stabilization, resulting in green afterglow while maintaining uniformity in size and morphology. Furthermore, the utility of CD-doped SiO(2) MPs in the fabrication of PC patterns is demonstrated, exhibiting multiple optical responses under different lighting conditions.

Summary: This study reports a method of fabricating an electrically responsive photonic crystal (ERPC) in weak polar media. The ERPC shows good performance due to less screening of Coulombic interaction. By using aniline as a weak polar solvent, the ERPC is fabricated without any charge-controlling agent. The resulting SiO2/ANI ERPC exhibits a broad reflection wavelength tuning range (230 nm) and a low working potential (1.4 V), leading to improved stability and reversibility of the electrical tuning.

Summary: This study proposes a new methodology for coloration inspired by the feather color change of a hummingbird. By integrating a view-angle dependent photonic diffraction grating pattern and voltage-actuated dielectric elastomers, a structure-colorable flexural artificial muscle (FlexAM) is developed. The FlexAM demonstrates ultrafast coloration and excellent fatigue resistance, and can be used in a photonic display device for displaying numbers and letters.

Summary: In this study, we developed inverse opal photonic crystals (IOPCs) that can function as real-time identifiable labels by adjusting the structure color and chemical color under UV and NIR light. The IOPCs were prepared by etching a silica photonic crystal template in a thermosensitive hydrogel containing NP. The combination of the green structure color of IOPCs and the red chemical color of the hydrogel resulted in the appearance of yellow color. The structure color of IOPCs changed from green to blue under NIR light, and when simultaneously irradiated by UV and NIR light, the IOPCs appeared purple due to the superimposition of the blue structure color and red chemical color.

Summary: In this study, Eu-doped YVO4 single crystals with different concentrations were fabricated to evaluate their photoluminescence and scintillation properties. The results showed that the samples doped with Eu exhibited emission peaks due to 4f-4f transitions in PL and scintillation spectra. Based on the pulse height spectra, the light yield of the Eu-doped samples increased with increasing Eu concentration, while the afterglow level decreased.
