Cold Flow as Versatile Approach for Stable and Highly Luminescent Quantum Dot–Salt Composites

Abstract: Since the beginning of the 1980s, colloidally synthesized quantum dots (QDs) have been in the focus of interest due to their possible implementation for color conversion, luminescent light concentrators, and lasing. For all these applications, the QDs benefit from being embedded into a host matrix to ensure stability and usability. Many different host materials used for this purpose still have their individual shortcomings. Here, we present a universal, fast, and flexible approach for the direct incorporation … Show more

“…[17] According to a previous publication we incorporated the resulting green-and orange-emitting InP/ZnS QDs into a protective KCl salt matrix. [23] Pressing the NC-loaded salt under cold flow conditions at 2.2 GPa results in composite materials which can be used as color conversion layers when stacked on top of a commercially available blue-emitting LED ( Figure 5, bottom). The corresponding PL spectrum and CIE diagram (x = 0.337, y = 0.333) of the white LED are shown in Figure 5 (top).…”

“…Впровадження квантових точок сферичної форми діаметром до 4 нм в йонні макрокристали солей описано у [5][6][7][8][9][10][11][12]. Одержані композити зберігають оптичні властивості при трансфері з розчину в кристал, володіють підвищеною стійкістю до впливу довкілля із набуттям фото-та хемостабільності.…”

“…У роботі [12] досліджено композити KCl:CdSe/CdS та KCl:CdSe/ZnS, які випромінюють червоне, зелене та жовте світло відповідно. Зразки для дослідження готували методом, схожим на виробництво твердих зразків для ІЧ-спектроскопії: спресовування порошку композитного кристалу, який містить наночастинки.…”
