Upconversion luminescent materials (UCLMs) have garnered significant attention due to their broad potential applications in fields such as display technology, biological imaging, and optical sensing. However, optimizing crystal phase morphology remains a challenge. This study systematically investigates the effects of transformation control on upconversion properties K3GaF6:Er3+. By comparing different synthesis methods, we found that hydrothermal method effectively facilitated NaxK3-xGaF6 from cubic monoclinic, with Na+/K+ ions playing key role preparation process. Furthermore, significantly optimized particle morphology, resulting formation uniform octahedral structures. The 657 nm red emission intensity monoclinic sample doped Er3+ was enhanced by 30 times compared phase, clearly demonstrating crucial performance. emphasizes synergistic optimization through engineering, which substantially improves luminescence efficiency K3GaF6:Er3+, paving way for further advancements design efficient materials.

Polymersomes are biomimetic cell membrane-like model structures that self-assembled stepwise from amphiphilic copolymers. These polymeric (nano)carriers have gained the scientific community’s attention due to their biocompatibility, versatility, and higher stability than liposomes. Their tunable properties, such as composition, size, shape, surface functional groups, extend encapsulation possibilities either hydrophilic or hydrophobic cargoes (or both) site-specific delivery. Besides, polymersomes can disassemble in response different stimuli, including light, for controlling “on-demand” release of cargo may also respond light photosensitizers plasmonic nanostructures.
