These scientists were studying a type of light called LEDs that are made using tiny particles called perovskite quantum dots. These LEDs are able to produce light very efficiently, but they don't last very long. The scientists wanted to find a way to make these LEDs last longer and work better.

To do this, they came up with a special treatment for the perovskite quantum dot films. They used two different chemicals that helped to make the quantum dots line up in a very neat and organized way. This made the LEDs work much better because the light could travel through them more easily.

After treating the quantum dot films with these chemicals, the scientists found that the LEDs were able to produce very bright red light at a lower voltage than before. This means they were more efficient. They also found that the LEDs were much more stable and lasted a lot longer than previous ones.

In simple terms, the scientists found a way to make these special lights shine brighter, last longer, and work better by using some clever chemistry tricks to organize the tiny particles that make up the light.
