For the past 25 years, Nanoco has been developing quantum dots (QDs) to enhance a variety of different technologies, but what exactly are they and how can they be used for such a wide range of applications? In the first of this Quantum Dots 101 series, we’ll go through some of the basics of QD technology. QDs are nanoparticles of […]
Short-wave infrared (SWIR) image sensors based on colloidal quantum dots (QDs) have progressed into commercial products over the past decade, with the first generation of SWIR cameras relying on PbS QDs. These early devices demonstrated that solution-processed QDs integrate well with monolithic CMOS readout integrated circuits (ROICs) and can deliver a high-performance alternative to incumbent InGaAs sensors.[1] However, the presence […]
We have previously introduced QD-CMOS technology, discussed applications and compared aspects of different SWIR sensing technologies. This post aims to introduce the most common commercial colloidal quantum dot (CQD) SWIR sensing materials. We will discuss important materials parameters, quality features and highlight Nanoco’s unique capabilities in this area. All materials are narrow bandgap semiconductors, enabling the ability to shift the […]
As part of our blog series on short wave infrared (SWIR) sensing, we first established the general concepts and subsequently provided an overview of various applications in this wavelength range (1000 – 3000 nm).[1,2] In this article, we will take a look at the range of SWIR sensing technologies and compare the most established InGaAs with a variety of emerging technologies, […]
We recently started a series of blog posts to explore short wave infrared (SWIR) imaging with a particular focus on emerging quantum dot (QD)-CMOS technology. The first post provided an introduction and established some of the fundamentals of why SWIR is an exciting part of the electromagnetic spectrum (1.0 – 3.0 µm) that holds a lot of potential for wider […]
Adoption of QDs in displays is on the rise! Counterpoint Research recently published double-digit revenue growth in 2024 (Double-digit Growth for Quantum Dot Film & Plate Revenues in 2024 on Increased Adoption). Highlights from the report include: The report emphasised that Apple’s adoption of QD displays “solidified quantum dots as the best color conversion solution for high-end MiniLED displays”. Growth […]
