Hauv qee thaj chaw ntug dej hiav txwv, vim Bioluminescence plankton tsoo hauv nthwv dej, hiav txwv thaum hmo ntuj qee zaus emits Teal teeb.Rare ntiaj teb hlaukuj emit lub teeb thaum stimulated, ntxiv xim thiab radiance rau cov khoom siv hluav taws xob. Txoj kev ua kom yuam kev, hais tias de Bettencourt Dias, yog kom tickle lawv f electrons.
Siv cov khoom siv hluav taws xob xws li lasers lossis teeb, cov kws tshawb fawb thiab cov kws tsim qauv tuaj yeem ua kom lub f electron nyob hauv lub ntiaj teb tsis tshua muaj zog rau lub xeev zoo siab thiab rov qab mus rau lub xeev dormant, lossis nws hauv av. Nws tau hais tias "Thaum Lanthanide rov qab los rau hauv av, lawv tawm lub teeb," nws hais
De Bettencourt Dias tau hais tias: Txhua yam ntawm lub ntiaj teb tsis tshua muaj kev ntseeg siab emits ib tug meej wavelength ntawm lub teeb thaum zoo siab. Qhov tseeb txhim khu kev qha no tso cai rau cov engineers ua tib zoo kho cov hluav taws xob hluav taws xob hauv ntau cov khoom siv hluav taws xob. Piv txwv li, lub luminescence wavelength ntawm terbium yog hais txog 545 nanometers, uas ua rau nws haum rau tsim ntsuab phosphors nyob rau hauv TV, computer, thiab smartphone cov ntxaij vab tshaus. Europium muaj ob hom qauv thiab siv los tsim cov phosphor liab thiab xiav. Hauv luv luv, cov phosphors tuaj yeem siv rau ntawm cov ntxaij vab tshaus Feem ntau cov xim ntawm zaj sawv yog kos rau ntawm qhov screen
Lub ntiaj teb tsis tshua muaj peev xwm emit lub teeb pom kev zoo. Yttrium yog qhov tseem ceeb ntawm Yttrium aluminium garnet lossis YAG. YAG yog ib tug hluavtaws siv lead ua, uas tsim cov tub ntxhais ntawm ntau lub zog lasers. Cov kws tshaj lij kho qhov wavelength ntawm cov lasers los ntawm kev ntxiv lwm lub ntiaj teb tsis tshua muaj rau YAG siv lead ua. Ntau yam nrov tshaj plaws yog neodymium doped YAG laser, uas yog siv rau ntau lub hom phiaj los ntawm kev txiav hlau kom tshem tawm tattoos mus rau laser ntau yam. Erbium YAG laser beams yog ib qho kev xaiv zoo rau cov txheej txheem Minimally invasive, vim tias lawv yooj yim absorbed los ntawm cov dej hauv lub cev, yog li lawv yuav tsis txiav tob heev.
Ntxiv nrog rau cov lasers,lanthanumNws yog ib qho tseem ceeb rau ua infrared absorbing tsom iav nyob rau hauv cov tsom iav hmo ntuj. Molecular engineer Tian Zhong los ntawm University of Chicago tau hais tias, "Erbium tsav peb internet. Feem ntau ntawm peb cov ntaub ntawv digital taug kev los ntawm fiber ntau optical hauv daim ntawv ntawm lub teeb nrog lub wavelength ntawm kwv yees li 1550 nanometers - tib lub wavelength li erbium emits. optic cables darken deb ntawm lawv qhov chaw vim tias cov cables no tuaj yeem txuas tau ntau txhiab mais ntawm seabed, erbium tau ntxiv rau cov fibers los txhim kho cov teeb liab
