Kwezinye izindawo ezisogwini, ngenxa yokugingqika kwe-Bioluminescence plankton emagagasini, ulwandle ebusuku ngezikhathi ezithile lukhipha ukukhanya kwe-Teal.Izinsimbi zomhlaba ezingavamileiphinde ikhiphe ukukhanya uma ikhuthazwa, ingeza umbala nokukhazimula emikhiqizweni ye-elekthronikhi. Iqhinga, kusho u-de Bettencourt Dias, ukukitaza ama-electron abo.
Besebenzisa imithombo yamandla njengamalaser noma amalambu, ososayensi nonjiniyela bangakwazi ukushintsha i-f electron emhlabeni ongavamile baye esimweni sokujabula bese bewubuyisela esimweni sokungalali, noma isimo sawo saphansi. "Uma iLanthanide ibuyela esimweni esiphansi, ikhipha ukukhanya," kusho yena
U-De Bettencourt Dias uthe: Uhlobo ngalunye lomhlaba olungavamile lukhipha ngokuthembekile ubude begagasi obunembile bokukhanya lapho ujabulile. Lokhu kunemba okuthembekile kuvumela onjiniyela ukuthi balungise ngokucophelela imisebe ye-electromagnetic emikhiqizweni eminingi ye-elekthronikhi. Isibonelo, ubude begagasi be-luminescence be-terbium cishe bungama-nanometers angu-545, okuyenza ifaneleke ukwakha ama-phosphor aluhlaza ku-TV, ikhompyutha, nezikrini ze-smartphone. I-Europium inezinhlobo ezimbili ezivamile futhi isetshenziselwa ukwakha i-phosphors ebomvu neluhlaza okwesibhakabhaka. Kafushane, lawa maphosphor angasetshenziswa ezikrinini Iningi lemibala yothingo lidwetshwa esikrinini.
Umhlaba ongavamile nawo ungakhipha ukukhanya okungabonakali okuwusizo. I-Yttrium iyingxenye ebalulekile ye-Yttrium aluminium garnet noma i-YAG. I-YAG iyikristalu yokwenziwa, eyakha umnyombo wamalaser amaningi anamandla aphezulu. Onjiniyela balungisa ubude begagasi balawa ma-laser ngokungeza enye into eyivelakancane yomhlaba ku-YAG crystal. Izinhlobonhlobo ezidume kakhulu i-neodymium doped YAG laser, esetshenziselwa izinhloso ezehlukene ukusuka ekusikeni insimbi kuye ekususeni ama-tattoos kuya ku-laser. Imishayo ye-laser ye-Erbium YAG iyisinqumo esihle senqubo yokuhlasela Kancane, ngoba imuncwa kalula amanzi emzimbeni, ngakho-ke ngeke ijule kakhulu.
Ngaphezu kwama-laser,i-lanthanumkubalulekile ekwenzeni izingilazi ezimunca infrared ezingilazini zokubona ebusuku. Unjiniyela wamangqamuzana u-Tian Zhong wase-University of Chicago uthe, "I-Erbium ishayela i-inthanethi yethu. Ulwazi lwethu oluningi lwedijithali luhamba ngama-optical fibers ngendlela yokukhanya okunobude obungaba ngu-1550 nanometers - ubude begagasi obufana ne-erbium ephumayo. Amasignali aku-fiber izintambo zokukhanya ziba mnyama kude nomthombo wazo Ngenxa yokuthi lezi zintambo zinganweba izinkulungwane zamakhilomitha olwandle, i-erbium yengezwa emiculweni ukuze kuthuthukiswe isignali.
