Abstract

Dual emission carbon dots (DE-CDs) have emerged as a transformative class of nanomaterials, offering distinct advantages over single-emission carbon dots (SE-CDs), including superior anti-interference capabilities, built-in self-calibration and broader full-width at half maximum (FWHM) emission spectra. This review comprehensively explores recent advancements in the synthesis of DE-CDs, detailing their physicochemical characteristics and elucidating key hypotheses underlying the formation of dual-emission peaks, such as the roles of core states, surface states, and quantum confinement effects. The diverse applications of DE-CDs are systematically analyzed, emphasizing their use in ratiometric sensing, bioimaging, biosensing, pH monitoring, moisture and water detection, and white light-emitting diodes (WLEDs). A comparative evaluation highlights their advantages and limitations relative to traditional fluorescence materials. Furthermore, recent progress in integrating DE-CDs into dye-sensitized solar cells (DSCs) and solar steam generation (SSG) devices is presented, underscoring their potential in renewable energy technologies. Finally, this review discusses the challenges and prospects for developing DE-CDs, including the need for scalable synthesis techniques, optimization of quantum yields for lighting applications, and enhanced understanding of dual-emission behavior mechanisms. Despite these challenges, DE-CDs hold immense promise for advancing technologies in sensing, bioimaging, lighting, and sustainable energy systems.
双排放碳点:合成、应用、进展与挑战
双发射碳点(DE-CDs)已经成为一种变革性的纳米材料,与单发射碳点(SE-CDs)相比,它具有明显的优势,包括优越的抗干扰能力、内置自校准和更宽的半最大值全宽度(FWHM)发射光谱。本文综述了DE-CDs合成的最新进展,详细介绍了它们的物理化学特性,并阐明了双发射峰形成的关键假设,如核心态、表面态和量子限制效应的作用。本文系统地分析了DE-CDs的各种应用,强调了它们在比率传感、生物成像、生物传感、pH监测、水分和水检测以及白光发光二极管(wled)中的应用。对比评价突出了它们相对于传统荧光材料的优点和局限性。此外,介绍了将DE-CDs集成到染料敏化太阳能电池(dsc)和太阳能蒸汽发生(SSG)设备中的最新进展,强调了它们在可再生能源技术中的潜力。最后,本文讨论了开发DE-CDs的挑战和前景,包括对可扩展合成技术的需求,照明应用的量子产率优化以及对双发射行为机制的进一步了解。尽管存在这些挑战,de - cd在推进传感、生物成像、照明和可持续能源系统技术方面仍具有巨大的前景。
