When a molecule emits a flash, emitted photons can not be returned. However, according to the website of the University of Cambridge, the university's research team at Jeremy J. Baumberg tried to put a single molecule in a tiny cavity and let it emit photons back into the molecule and leave it when it is needed, leaving the energy at Light and molecules oscillate back and forth to form a quantum-state strong coupling of molecules and light. This result helps to develop quantum technology and new ways of controlling the physical and chemical properties of matter.

Source: University of Cambridge Previous attempts to mix molecules and light were complicated and were usually achieved at very low temperatures. The new method produces these "semi-luminescent" molecules at room temperature. The Baumberg team surrounded the tiny "corridors" with gold nanoparticles and gold atoms and placed methylene blue dye molecules inside. Gold atomic film is like a mirror, surrounded by a diameter of about 1 nanometer "mirror gallery", to become trapped light cavity. Baumberg says: "Although a hair is hundreds of thousands of times thinner than a hair, it is like a mirror for a molecule." In order to achieve molecular and light mixing, but also to dye molecules in the "mirror gallery" to maintain an upright position. Rohit Chikkaraddy, the lead author of the research paper, said it is hard for ordinary people to lie flat on the gold film, making it hard for them to "stand up." They put the dye molecules into a barrel-shaped molecular cage called a "cucurbit" to keep it upright and start experimenting. Eventually they found that the molecular scattering spectrum splits into two separate quantum states, a "hybrid" signature that reflects the photons returning to the molecule in less than one trillionth of a second. Chikkaraddy said that in order to find such a signature, they spent months collecting data. One of the key points of the study is to prove that for a single molecule, strong mixing of light and matter is possible even at room temperature with a strong absorption of light by the metal.
