Abstract Long‐life room temperature phosphorescent (RTP) materials hold significant potential in the fields of optoelectronic devices, information encryption, and bio‐imaging due to their excellent optical properties. However, achieving multi‐color tunable RTP has proven challenging. In this study, molecular engineering strategies are employed select precursor molecules with varying degrees conjugation such as phthalic anhydride (PA), naphtho[2,3‐c] furan‐1,3‐dione (23NA), naphthalic (NA). By combining these guest a host boric acid matrix through one‐step microwave method, carbon dots (CDs)composites (PA@BA, 23NA@BA NA@BA) exhibiting properties successfully prepared. As degree increased gradually, phosphorescence color modulation composites demonstrates satisfactory transitions from blue yellow. Notably, CDs derived situ within while covalent hydrogen bonds formed between borate effectively suppress nonradiative leaps facilitate composite activation. Furthermore, acts insulation against oxygen diffusion prevents quenching triplet excitons by external factors. The rationality behind emission mechanism wavelength is further conformed density functional theory (DFT) calculations. Finally, applied for advanced message encryption text images.

Abstract Stimuli‐responsive photoluminescent (PL) materials have attracted considerable attention in recent years owing to their potential applications anti‐counterfeiting, information encryption, and sensing. Further investigations of the transformation mechanism stimulus‐responsive PL are considerably important. In current study, an organic–inorganic metal halide, C 9 H 15 N 3 SbCl 5 ([C 13 ] 2+ is a 1‐(2‐pyridyl) piperazine cation) obtained, which exhibits 0D structure with P‐ 1 space group. At room temperature, when excited by UV light, single crystals exhibit unimodal blue light emission at 405 nm, grinding or hydrostatic pressure induces double‐peak emissions 650 nm. Interestingly, double‐emission samples can be restored single‐emission short annealing storage air for 2 weeks, this process reversible. Luminescence response mechanical stimuli also achieved presence hydrochloric acid water. Spectral analysis microstructural changes revealed that structural modifications inorganic group play pivotal role stimulus. Finally, composite film device based on prepared demonstrate these smart anti‐counterfeiting sensing applications.

Abstract Zero‐dimensional (0D) hybrid metal halides have been emerged as room‐temperature phosphorescence (RTP) materials, but synchronous optimization of multiple performance in one structural platform remains less resolved, and stable RTP activity aqueous medium is also unrealized due to serious instability toward water oxygen. Herein, we demonstrated a photophysical tuning strategy new 0D zinc halide family (BTPP) 2 ZnX 4 (BTPP=benzyltriphenylphosphonium, X=Cl Br). Infrequently, the delicate combination organic inorganic species enables this display ultralong green afterglow efficient self‐trapped exciton (STE) associated cyan phosphorescence. Compared with inert luminescence [BTPP] + cation, incorporation anionic [ZnX ] 2− effectively enhance spin‐orbit coupling effect, which significantly boosts photoluminescence quantum yield (PLQY) up 30.66 % 54.62 for phosphorescence, respectively. Synchronously, corresponding lifetime extend 143.94 ms 0.308 μ s surpassing indiscernible [BTPP]X salt. More importantly, presents robust emission nearly unattenuated PLQY harsh condition (acid basic solution) over half year. The highly integrated STE well ultrahigh state realize anti‐counterfeiting applications wide chemical environments.
