Nyob rau hauv qee thaj chaw ntug hiav txwv, vim yog bioluminescence plankton tsoo hauv nthwv dej, hiav txwv thaum qee zaum teal teeb.Lub ntiaj teb tsis tshua muaj hlauKuj tseem emit teeb thaum ua kom muaj txiaj ntsig, ntxiv xim thiab radiance mus rau cov khoom siv hluav taws xob. Qhov ua kom yuam kev, hais tias dias saltencourt dias, yog kom zuam lawv cov hluav taws xob.
Siv cov peev txheej hluav taws xob xws li lasers lossis roj teeb, cov kws tshawb fawb thiab cov kws ua haujlwm tau oscillate ib lub ntiaj teb tsis tshua muaj zoo rau lub xeev dormant, lossis lub xeev ruaj khov. "Thaum Lanthhanide rov qab mus rau hauv av lub xeev, lawv emit teeb," nws tau hais
Dib bettencourt dias tau hais: txhua hom tsis tshua muaj lub ntiaj teb ntseeg kom pom tseeb ntawm lub teeb thaum zoo siab. Qhov kev ntseeg tau zoo no pub rau cov encessorating kom ua tib zoo kho hluav taws xob hluav taws xob hauv ntau yam khoom siv hluav taws xob. Piv txwv li, lub luminescence wavelength ntawm terbium yog kwv yees li 545 nanometers, uas ua rau nws tsim cov kuab ntsuab hauv TV, khoos phis tawj, thiab smartphone ntxaij. Europium muaj ob hom ntawv sib xws thiab siv los tsim cov xim liab thiab xiav phosphors. Hauv ntej, cov phosphors no tuaj yeem siv rau cov ntxaij feem ntau ntawm cov xim ntawm zaj sawv yog kos rau ntawm lub vijtsam
Lub ntiaj teb tsawg kuj tseem tuaj yeem tawm cov teeb pom kev zoo. Yttrium yog qhov tseem ceeb ntawm yttrium aluminium garnet lossis yag. Yag yog cov khoom siv hluavtaws, uas ua rau cov tub ntxhais muaj ntau lub high-hwj chim lasers. Cov engineers hloov lub wavelength ntawm cov lasers los ntawm kev ntxiv lwm lub ntiaj teb tsis tshua muaj cov av hauv ntiaj teb mus rau cov Yag Crystal. Cov nrov tshaj plaws yog ntau yam yog neodymium doped yag laser, uas yog siv rau ntau lub hom phiaj los tshem cov tattoos mus rau laser rau laser rau txoj kev siv laser. Erbium YAG Laser Beams yog qhov kev xaiv zoo rau cov txheej txheem tsis zoo, vim tias lawv tau yooj yim nqus los ntawm cov dej hauv lub cev, yog li lawv yuav tsis txiav sib sib zog nqus.
Ntxiv nrog rau lasers,lus qhiayog qhov tseem ceeb rau kev ua cov iav infrarbing nqus tau lub tsom iav tsaus ntuj. Molecular engineer tian zhong los ntawm University of Chicago hais tias, "Elbium tsav thoob plaws 1550 tus xov tooj hluav taws xob mus ntxiv los ntawm ntau txhiab mais ntawm lub hiav txwv, erbium ntxiv rau cov fibers los txhim kho lub teeb liab
