bulbs

So far, 11 unique minerals have been discovered on the Moon. The last of them has just been revealed by a team of Chinese scientists after analyzing a lunar meteorite. It is an interesting finding, because it gives us useful information about the geology of our satellite. But also because it could have very interesting applications here on Earth. From the Moon to your light bulbs. The material just described It is cerium-magnesium changesite. It is characterized by its glassy, ​​transparent and brittle appearance. The thickness of its granules ranges from 3 to 25 micrometers, less than that of a human hair. Still, it is extremely useful due to its pronounced fluorescence, which could be very useful in improving terrestrial LED technology. A necessary color change. Unlike traditional incandescent bulbs, LED bulbs do not use heat to produce light. They make the most of electricity thanks to a semiconductor material, which allows the flow of electrons from a layer with an excess charge to another with a lack of it. That second layer has what are known as voids. That is, atoms that have lost electrons, leaving something like a free hole. The moment an electron encounters one of these holes, falls inside, in a process in which energy is released in the form of light. The light obtained in this process is blue, but we have all seen that, in general, the light from LEDs is white. The color change is achieved thanks to the coating the bluish chip in which the process occurs with a fluorescent material. This absorbs some of the blue light and, in turn, emits yellow light. Both are what are known as complementary colors of light. Therefore, when you mix them you obtain white light. The more fluorescence, the better. The fluorescence of this lunar mineral is so powerful that it would be a wonderful complement to LED bulbs. White light would be obtained in a much more efficient way, resulting in even greater energy savings. More achievements for China. The Asian country has become an expert in lunar geology, thanks to the Chang’e missions. In fact, the Changesite-(Y) phosphate was already discovered on Chang’e-5, directly related to this other mineral that a meteorite brought to Earth. For now, we can only dream. Logically, going to the Moon to excavate minerals is not very viable. And if it were, it would be good to think twice before jumping in headfirst. We also don’t know if there would be enough on the Moon. It would be necessary to explore it further to know. Therefore, the applications of lunar minerals in terrestrial technology are nothing more than hypotheses. It is interesting, but it does not have a close application in time. What these minerals do teach us. Analysis of lunar geology It can teach us many things. If we find mostly minerals that also exist here on Earth, we can understand that, at some point, similar conditions existed on Earth and the Moon. On the other hand, if many unknown minerals are found on Earth, as is already happening, it is understood that there were conditions on our satellite that have not occurred on our planet. All this serves to understand very well where we are and where we come from. Let’s stay with that instead of thinking about mining our satellite and leaving it without resources as we are already beginning to do on Earth.
