However, a key problem with most modern lasers is that they emit light at fixed wavelengths. This limitation can be overcome using quantum dots, nanoscale semiconductors that can emit light of ...

Quantum dot FP lasers have an ensemble of self-assembled QDs inside the cavity as shown in Fig. 1. By simply modulating the laser's injection current, the laser emits a stream of digital data bits ...

In the past few years, colloidal quantum dots – solution-processed semiconducting nanocrystals – have emerged as an alternative for mainstream consumer electronics. While toxic heavy-metals, such as ...

Quantum dots are nanoscale man-made crystals that have the ability to convert a spectrum of light into different colors. Each dot emits a different color depending on its size. (Image: RNGS ...

These include Light Detection and Ranging (LIDAR), a method for determining ranges and distances using lasers ... In the past few years, colloidal quantum dots—solution-processed semiconducting ...

In a study published in the journal Optical Materials Express, Strathclyde researchers detail how they recycled quantum dots ...

Particular interests are wide band gap materials (AlGaInP and (Al)InGaN) for visible and uv light emitters and quantum dots for high efficiency lasers and novel light emitters. I was the first person ...

Colloidal quantum dots (QDs) are semiconductor nanocrystals ... QDs reported previously are often excited by femtosecond pulsed lasers, which have a large size (comparable to a computer tower ...
