However, achieving efficient red\/NIR RTP emitters has been challenging due to the weak spin\u2010orbit coupling of organics and the rapid nonradiative decay imposed by the energy gap law. Here we demonstrate highly efficient red\/NIR RTP with boosted quantum yields (\n                    <jats:italic>\u03a6<\/jats:italic>\n                    <jats:sub>p<\/jats:sub>\n                    s) of up to 32.96\u2009% through doping the thionated derivatives of phthalimide (PAI) (MTPAI and DTPAI) into PAI crystals. The red\u2010shifted photoluminescence (PL) stems from a combination of the external heavy atom effect and the formation of emissive clusters centered around electron\u2010rich sulfur atoms. Furthermore, the dopants enhance exciton generation efficiency and facilitate energy transfer from smaller PAI units to larger aggregates, leading to dramatically increased\n                    <jats:italic>\u03a6<\/jats:italic>\n                    <jats:sub>p<\/jats:sub>\n                    . This strategy proves universal, opening possibilities for acquiring long\u2010wavelength RTP with tunable photophysical properties. The doped crystals exhibit promising applications in optical waveguides and encryption paper\/ink. This research provides a practical approach to obtaining long\u2010wavelength RTP materials and offers valuable insights into the mechanisms governing host\u2010guest systems.\n
