Mune dzimwe nzvimbo dzemahombekombe, nekuda kweBioluminescence plankton inorovera mumasaisai, gungwa usiku rinomboburitsa chiedza cheTeal.Rare earth metalszvakare inoburitsa chiedza kana ichikurudzirwa, ichiwedzera ruvara uye kupenya kune zvigadzirwa zvemagetsi. Manomano, anodaro de Bettencourt Dias, kukwenya ma electrons avo.
Vachishandisa masimba emagetsi akadai semalaser kana marambi, masayendisiti nemainjiniya vanogona kutenderedza maerekitironi mupasi risingawanikwe kuenda kunzvimbo ine mafaro vozoidzosera kune yakarara, kana kuti pasi pasi. "Lanthanide painodzokera pasi, inoburitsa mwenje," akadaro
De Bettencourt Dias akati: Rudzi rwega rwega rwepasi risingawanzo buditsa nenzira yakavimbika urefu hwechiedza chaihwo kana hwanakidzwa. Uku kurongeka kwakavimbika kunobvumira mainjiniya kunyatso gadzirisa radiation yemagetsi mune zvakawanda zvigadzirwa zvemagetsi. Semuenzaniso, luminescence wavelength yeterbium ingangoita 545 nanometers, izvo zvinoita kuti ive yakakodzera kuvaka green phosphors muTV, komputa, uye smartphone skrini. Europium ine mafomu maviri akajairika uye inoshandiswa kugadzira tsvuku uye bhuruu phosphors. Muchidimbu, maphosphors aya anogona kushandiswa pachiratidziro Mazhinji emavara emurarabungu anodhirowewa pachiratidziri.
Mapasi asingawanzo kubudisa chiedza chisingaoneki chinobatsira. Yttrium ndicho chinhu chakakosha cheYttrium aluminium garnet kana YAG. YAG ikristaro yakagadzirwa, iyo inoumba musimboti weakawanda epamusoro-simba lasers. Mainjiniya anogadzirisa kureba kweaya lasers nekuwedzera chimwe chisingawanzo chepasi chinhu kune YAG crystal. Iwo anonyanya kufarirwa akasiyana ndeye neodymium doped YAG laser, iyo inoshandiswa kune zvakasiyana siyana kubva pakucheka simbi kusvika pakubvisa ma tatoo kusvika laser kubva. Erbium YAG laser matanda isarudzo yakanaka yeMinimally invasive maitiro, nekuti anotorwa nyore nyore nemvura iri mumuviri, saka haazocheka zvakanyanya.
Mukuwedzera kune lasers,lanthanumyakakosha pakugadzira magirazi anotora infrared mumagirazi ekuona husiku. Muinjiniya weMolecular Tian Zhong wekuUniversity yeChicago akati, "Erbium inofambisa indaneti yedu. Ruzhinji rweruzivo rwedu rwedhijitari rwunofamba nemaoptical fibers muchimiro chechiedza chine wavelength inosvika 1550 nanometers - wavelength yakafanana neerbium inoburitsa. Masaini mufiber tambo dzemaziso dzinosviba kure nekwadzinobva nekuti tambo idzi dzinogona kuwedzera zviuru zvemakiromita pasi pegungwa, erbium inowedzerwa kumafayibha kuti iwedzere chiratidzo.
