Nobel Prize in Chemistry 2023: In the 1939 film The Wizard of Oz, the protagonist Dorothy was transported from a black-and-white and sepia-toned world to a magical, technicolour realm because her house was swept away by a powerful tornado. While this is just a fictional movie, such scenarios occur in real life. In the world of nano dimensions, where everything is extremely tiny, the properties of particles change, and so do the colours emitted by them. This is because of the quantum effects that
