Here, we report an amphiphilic polymer chain\u2010driven in situ curing strategy that generates rigid luminescent epoxy microspheres uniformly within a PVA hydrogel matrix. Combined with annealing\u2013reswelling\u2010induced matrix densification, this process creates a spatially synergistic dual\u2010confinement system, in which the inner epoxy domains immobilize phosphors while the outer dense PVA network helps impede the ingress of water and oxygen. The resulting hydrogels exhibit tunable multicolor RTP, an ultralong phosphorescence lifetime of up to 4342\u00a0ms, a daylight\u2010visible afterglow luminance of 87.9\u00a0cd m\n                    <jats:sup>\u22122<\/jats:sup>\n                    , a time\u2010gated delayed\u2010emission quantum yield of 55.49%, and a tensile strength exceeding 10\u00a0MPa. Notably, the hydrogels retain a phosphorescence lifetime of 3172\u00a0ms after 170 days of water immersion. This work identifies spatially synergistic dual confinement as an effective route to jointly optimize phosphorescence efficiency, mechanical robustness, and long\u2010term underwater stability in soft luminescent hydrogels.\n                  <\/jats:p>","DOI":"10.1002\/adma.74914","type":"journal-article","created":{"date-parts":[[2026,9,2]],"date-time":"2026-09-02T13:48:09Z","timestamp":1788356889000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Spatially Synergistic Dual\u2010Confinement Enables Underwater\u2010Stable Room\u2010Temperature Phosphorescent Hydrogels"],"prefix":"10.1002","volume":"38","author":[{"given":"Lei","family":"Liu","sequence":"first","affiliation":[{"name":"School of Materials Science and Engineering Chongqing University of Technology  Chongqing P.
