A simple structural tweak has dramatically enhanced the colour clarity and stability of heavy metal-free blue quantum dots.

A research team has devised a novel method to prepare carbonized polymer nanodots capable of emitting multi-color ultra-long room-temperature phosphorescence (RTP) from blue to green. "These ...

If you’ve texted on your Android phone, you may have noticed that some contacts have a small blue dot or a chat bubble on the bottom right of their profile picture. RCS messaging also likely ...

Each dot emits a different color depending on its size. (Image: RNGS Reuters/Nanosys) Quantum dots are artificial nanostructures that can possess many varied properties, depending on their material ...
