Abstract Luminescent materials with time‐resolved dynamic discoloring afterglow (TDDA) hold significant potential for applications in anti‐counterfeiting and data encryption. However, the afterglows coming from organic systems are usually unidentifiable due to their shorter durations (less than 10 s). Achievement of long‐lasting visually discernible TDDA remains highly desirable but challenging. In this work, duration is successfully extended less s minutes by engineering luminescent centers carbon dots (CDs) introducing deep trap‐states a composite CDs nitrides (CNs) (named Y‐CDs@CN). It confirmed that regulation containing both C═N C═O bonds responsible color changes during yellow green. Moreover, generation trap states found be prolonging level through converting room temperature phosphorescence into long persistent luminescence, thus making entire process being easily recognized naked eyes. Furthermore, Y‐CDs@CN can also excited blue light even using white cell phone. To harness these characteristics, portable multidimensional information encryption primarily investigated.

Over the years, oral and maxillofacial injuries, mainly caries, pulpitis, bone defects, cancer, often involve a variety of organs tissues, resulting in structural dysfunction, adverse effects on facial appearance, not only affecting people's chewing, swallowing other physiological functions, but also to physical mental health burden. As type carbon-based nanomaterial, carbon dots (CDs) have been widely used diagnosis treatment diseases due its excellent optical properties, good biocompatibility low toxicity. In addition, surface functionalization or passivation CDs can change properties CDs, such as water solubility chemiluminescence, broaden biomedical potential CDs. this review, latest research progress modified hard tissue regeneration, tumor treatment, antibacterial activity, dentin pulp complex teeth whitening, wound healing, drug release, fluorescence tracer bioimaging were reviewed. we discussed problems future direction development.
