“…Following the UV treatment, a significant improvement in the red color content of the LED was observed and CRI of the white LED increased from 87.2 to 91.0. In 2014 Liang et al developed controllable incorporation of the QDs into poly(vinyl alcohol) (PVA) matrix to obtain flexible color converters [20]. In this work, single color QDs (green, yellow, orange, and red) were blended within PVA solution to obtain negatively charged QD cluster suspensions.…”

Recent advances in colloidal synthesis of nanocrystals have enabled high-quality high-efficiency light-emitting diodes, displays with significantly broader color gamut, and optically-pumped lasers spanning the whole visible regime. Here we review these colloidal platforms covering the milestone studies together with recent developments. In the review, we focus on the devices made of colloidal quantum dots (nanocrystals), colloidal quantum rods (nanorods), and colloidal quantum wells (nanoplatelets) as well as those of solution processed perovskites and phosphor nanocrystals. The review starts with an introduction to colloidal nanocrystal photonics emphasizing the importance of colloidal materials for light-emitting devices. Subsequently, we continue with the summary of important reports on light-emitting diodes, in which colloids are used as the color converters and then as the emissive layers in electroluminescent devices. Also, we review the developments in color enrichment and electroluminescent displays. Next, we present a summary of important reports on the lasing of colloidal semiconductors. Finally, we summarize and conclude the review presenting a future outlook.

“…Using self-assembly of triple building blocks, LDH nanoplatelets, polyvinyl alcohol (PVA), and quantum dots (QDs: CdTe or CdSe/ZnS), flexible films were fabricated that were found to be highly luminescent (strong fluorescence and high fluorescence quantum yield) with finely tunable fluorescence (green, yellow, orange, and red) as well as a high photo-and thermostability.

Two‐Dimensional Hybrid Materials: Transferring Technology from Biology to Society

et al. 2015

Hybrid materials are at the forefront of modern research and technology; hence a large number of publications on hybrid materials has already appeared in the scientific literature. This essay focuses on the specifics and peculiarities of hybrid materials based on two‐dimensional (2D) building blocks and confinements, for two reasons: (1) 2D materials have a very broad field of application, but they also illustrate many of the scientific challenges the community faces, both on a fundamental and an application level; (2) all authors of this essay are involved in research on 2D materials, but their perspective and vision of how the field will develop in the future and how it is possible to benefit from these new developments are rooted in very different scientific subfields. The current article will thus present a personal, yet quite broad, account of how hybrid materials, specifically 2D hybrid materials, will provide means to aid modern societies in fields as different as healthcare and energy.

“…Therefore, QDs are also called "nanocrystals" and "artificial atoms." Recently, QDs have drawn extensive attention in various fields due to their unique opticalelectrical properties [4][5][6][7][8][9]. For example, the size-dependant emission spectra of QDs can be freely tuned in the visible range during the synthesis process and excited by the certain wavelength [4].…”

We demonstrated the inkjet-printed CdTe quantum dots-polyurethane acrylate thin films and their potential application in the display devices. The water soluble CdTe QDs were synthesized through the wet chemistry and the emission wavelengths can be freely tuned during the preparation process. Combining with the UV curable resin polyurethane acrylate, the QDs inks were prepared and the influence of diluent and water content on the performance of resultant films was studied. The tensile stress of the films cured from the QDs inks with diluent increased from 10.6 MPa to 27.5 MPa and the low water content led to uniform polymer matrix. Furthermore, the existence of diluent and low water content would all improve the fluorescence stability of the thin films. Finally, the thin films can be deposited on different substrates and well controlled to meet the RGB color standard, which will pave the way to a simple, low-cost, large-scale, and highly reliable method for the application of flexible displays.
