Designing all-CArbon-based colour tunable Random Lasers for speckle free Imaging applicaTiOns (CARLITO)

Context: Applications of traditional lasers are often hindered by unavoidable difficulties related to their bulky, expensive and highly coherent nature. The fabrication of lasers is tricky in itself as it requires a tightly geometrically-controlled resonant cavity. A way to overcome these problems is obtaining laser emission from the random walk of photons in a disordered medium, also known as a random laser (RL). Unfortunately, achieving efficient, tunable, and stable RL remains still difficult. A plethora of nanostructured metals and semiconductors were proposed as passive or active scatterers, while organic dyes and quantum dots (QDs) are explored as gain media. Yet, organic dyes usually suffer from rapid photo-bleaching, while semiconductor QDs are affected by fluorescence blinking, and their toxicity can be a serious pitfall in biomedical RL applications. Some reports have focused on using naturally available scatterers for RL, but these devices are limited by low tunability and repeatability. In CARLITO project we propose the use of carbon nanostructured materials, such as carbon dots (CDs) as engineered nanostructures to design a new class of RLs for a wide range of photonic applications. The goal of CARLITO is to designing the first all-carbon-based RL device, which exploits hybrid carbon nanomaterials to achieve tunable and stable RL with low threshold. Key objectives of CARLITO are briefly summarized as follows. Overall Objectives: (1) Developing a new family of low-cost and fully biocompatible RL devices, which can be easily tuned to emit photons within the entire visible wavelength region. (2) Production of a set of luminescent carbon dots (CDs) with narrow band emission and high photoluminescence quantum yield, for their application as gain media in RLs. (3) Providing a general and repeatable strategy for (i) reducing the absorption and scattering loss in the CDs for their application as gain media, and (ii) designing of carbon-based scatterers. (4) Developing prototypes of flexible and biocompatible RLs, fulfilling well-defined performance benchmarks.

Цел на проекта

The practical application of conventional lasers is often hampered by inherent difficulties related to their bulky, expensive and highly coherent nature. Some of these issues can be overcome by so-called Random Lasers (RL), devices in which laser emission stems from the random walk of photons in a disordered medium. However, achieving efficient, tunable, and stable RL remains difficult to date. A large variety of nanostructured metals and semiconductors, organic dyes and quantum dots (QDs) were proposed as passive or active scatterers to fabricate RLs. However, organic dyes usually suffer from rapid photo-bleaching, while semiconductor QDs are affected by fluorescence blinking and their toxicity can be a serious pitfall in biomedical RL applications. CARLITO proposes the use of carbon nanostructured materials (CNMs) to design an entirely new class of RLs for a wide range of photonic applications, where a stable and low-threshold RL is obtained by the combined use of different CNMs as active and passive light scatterers. The ambitious goal of CARLITO is designing the first all-carbon-based RL (ACRL), capable to yield high-quality RL from hybrid CNMs, by taking advantage of the peculiar electronic properties of different zero-, one- and two-dimensional nanocarbons. ACRLs will be a new family of low-cost, non-toxic and fully biocompatible RL devices, which can be easily tuned to emit photons within the entire visible spectral region. Achieving these targets will advance RLs well beyond the current state-of-the-art, favouring their transition into real-world technology, such as in live cell microscopy, speckle free imaging and sensing. In particular, the application of ACRLs in speckle free imaging will be directly tested within the scope of CARLITO.
