In recent years, I‐III‐VI semiconductor quantum dots (QDs) have shown significant improvements that have unlocked new capabilities and end markets. Some typical examples of I‐III‐VI QDs are CuAlS2 (blue), AgInS2 (green), CuInSe2 (red) CuInSe2 (near‐IR), but other compositions and alloys are possible. These materials exhibit tunable photoluminescence (PL) emissions, and can achieve near unity PL quantum yield. They can have efficient broad emission, but also can have narrow emission, large Stokes shifts, and high optical extinction coefficients. These materials are often more stable, safer, and lower cost than alternatives such as CdSe, InP, and PbS or PbSe QDs. In this work, we discuss industrialization and scale‐up of I‐III‐VI QDs, starting with critical end uses related to spectrum optimization for greenhouses and solar energy. We also update on recent progress narrowing the emission linewidth (full‐width at half maximum) of I‐III‐VI QDs to the point that they are becoming competitive with legacy QDs used in displays and lighting.

Cadmium-based alloyed quantum dots are one of the most popular metal chalcogenides in both the industrial and research fields owing to their extraordinary optical and electronic properties that can be manipulated by varying the compositional ratio in addition to size control. This report aims to cover the main information concerning the synthesis techniques, properties, and applications of Cd-based alloyed quantum dots. It provides a comprehensive overview of the most common synthesis methods for these QDs, which include hot injection, co-precipitation, successive ionic layer adsorption and reaction, hydrothermal, and microwave-assisted synthesis methods. This detailed literature highlights the optical and structural properties of both ternary and quaternary quantum dots. Also, this review provides the high-potential applications of various alloyed quantum dots.

“…On the other hand, the existence of colloidal nanocrystals of semiconductor materials known as quantum dots (QDs) has facilitated their integration into LEDs fabrication due to their notable photoluminescence quantum yield, photochemical stability, wide absorption, and narrow emission spectra ( Liu and Su, 2014 ; Cao and An, 2015 ; Zhang et al, 2015 ; Su et al, 2020 ; Muñoz et al, 2021 ; Chen et al, 2022 ).…”

Integration of ternary I-III-VI quantum dots in light-emitting diodes

Ternary I-III-VI quantum dots (TQDs) are semiconductor nanomaterials that have been gradually incorporated in the fabrication of light-emitting diodes (LEDs) over the last 10 years due to their physicochemical and photoluminescence properties, such as adequate quantum yield values, tunable wavelength emission, and easy synthesis strategies, but mainly because of their low toxicity that allows them to be excellent candidates to compete with conventional Cd-Pb-based QDs. This review addresses the different strategies to obtain TQDs and how synthesis conditions influence their physicochemical properties, followed by the LEDs parameters achieved using TQDs. The second part of the review summarizes how TQDs are integrated into LEDs and white light-emitting diodes (WLEDs). Furthermore, an insight into the state-of-the-art LEDs development using TQDs, including its advantages and disadvantages and the challenges to overcome, is presented at the end of the review.
