We are all familiar with the constant evolution of technology. It is even expected to have new devices or improved services on a regular basis. One can hardly imagine life without technology, and this is not just about mobile phone. Sometimes high hopes are raised about what science can produce, as, recently, high hopes for a specific anti-covid vaccine. But, most of the time, we do not even suspect what science could do to improve even furthermore our everyday life. Attonuclei makes special announcements on a website about quantum dots. It is interesting to have a look on this website on a regular basis. The theme of their research is how to improve quantum dots. This is incredible because quantum dots are artificial, the researchers make them. The scientists in the 21st century are prolonging the revolutions started in the previous century. Everyone has heard about atoms. Quantum dots are like small entities, they have several components and can have three dimensions, they are compared with crystals. They are almost invisible, they are as tiny as a human hair. They have the function to be semiconductor, they request light to be activated. To put it very simply, according to the intensity of the activation, through UV lights for example, they can produce different colours. This capacity has many perspectives of developments.
What are the possible applications of the use of quantum dots ?
Since quantum dots are minuscule, their possible use in electronics and optical are radically different from bigger elements. For example, they are contributing to researches to develop sustainability and greater efficiency in detecting cancers through medical imagery in the future. The sectors concerned by the development of quantum dots are :
- biotechnology
- electronics
- materials
So, what can we expect from the development of building tiny crystals in laboratories ? From a visual perspective, the first popular result would be a great enhancement in the quality of colours of our screens. On our phones or TV screens, the colours would be a lot more vivid and deep. This enhancement would be energy saving, which makes it all the more appealing. Another great expectations that will be a great success once available is the capacity though the use of quantum dot technology in chargers for the phones. The first results of the research indicate that one minute only would be necessary to fully charge a phone with no more battery. One minute ! Let’s imagine all the economy of energy on the planet, thankfully to this development ! This kind of insight provides for a relief about the planet and hopes for a better world. In medicine, because the markers created by quantum dots are more stable than organic ones, it would allow checking rapidly and safely the irradiation of carers during the treatment of cancers. Regarding energy savings, since quantum dots produce lights, they are useful to improve the duration of LED and to decrease the production costs. Same about the photovoltaic. The duration and intensity of solar cells could be improved in a near future, thus enhancing the sustainability of such solutions to produce energy. We can assess that the future is bright !
