Tsis ntev los no, Shawn-YuLin, tus kws tshaj lij kho mob ntawm Rensselaer lub koom haum thev naus laus zis tau luam tawm daim ntawv tshiab hauv phau ntawv Journal of natural science report, hais tias tam sim no cov kws tshawb fawb tau pom ib yam khoom siv uas lub zog luminous siv tshaj li qhov txwv tsis pub muaj hluav taws xob ntau. Cov khoom siv tshiab no tuaj yeem siv hauv kev sau zog, tub rog tub rog infrared khoom taug thiab paub, tshawb pom atmospheric chemical spectroscopy tshawb, laser thiab lwm cov teb.
Thaum ntxov 19 ntawm lub xyoo pua, Max Planck, tus kws kho mob lub teb chaws German, tau siv cov qauv kev piav qhia los piav qhia txog txoj cai ntawm hluav taws xob thiab kwv yees tias lub zog tsuas muaj nyob hauv kev txiav txim siab qhov tseem ceeb, yog li nkag mus rau hauv quantum era. Max kuj tau lub npe tus tsim ntawm quantum mechanics. Txij li qhov kawg ntawm 19 ntawm lub xyoo pua, peb tau paub tias txhua cov ntaub ntawv tawm lub teeb nyob rau hauv qhov kev kwv yees lub teeb ntev thaum rhaub. Raws li Planck' s txoj cai, tsis muaj ib yam khoom hauv ntiaj teb tuaj yeem tshaj tawm hluav taws xob ntau dua li tus neeg dub. Neeg Dub yog ib qho khoom siv zoo tagnrho. Nws tuaj yeem nqus tag nrho cov hluav taws xob hluav taws xob sab nraud tawm sab nraud yam tsis muaj kev xav thiab xa mus. Nrog sawv ntawm qhov kub thiab txias, hluav taws xob electromagnetic thiab lub teeb ci tawm los ntawm lwm tus neeg hu ua blackbody radiation.
Shawn Yulin pom tias cov khoom siv tshiab tau ua txhaum cov kev txwv ntawm Planck' s txoj cai lij choj. Nws yog peb lub ntsej muag photonic siv lead ua raws li tungsten (zoo ib yam li pob zeb diamond siv lead ua hauv cov qauv). Thaum rhuab mus txog 600 k, nws qhov kev siv luminous yog 8 lub sijhawm ntawm tus txheej txheem dub, thiab cov qauv ntaub ntawv qhia tau lub qov hluav taws xob qhov siab txog li ntawm 1. 7 μ M. The cov ntaub ntawv tshiab tuaj yeem tawm ntawm lub teeb zoo sib xws los ntawm cov lasers lossis cov khoom siv hluav taws xob ua si (LEDs), tab sis lawv tsis xav tau cov qauv hluav taws xob zoo thiab kim.
Shawn Yulin tau hais tias qhov tseeb, qhov no tsis ua txhaum Planck' s txoj cai lij choj, tab sis yog txoj hauv kev tshiab los tsim kom muaj cua sov. Txawm hais tias txoj kev xav tsis tuaj yeem piav qhia txog qhov tshwm sim no, cov kws tshawb fawb xav tias qhov hloov ntawm cov khaubncaws sab nraud povtseg ntawm photonic siv lead ua tso cai rau lub teeb tua tawm ntawm qhov chaw sab hauv ntawm cov khoom siv lead ua, thiab lub teeb tawm ntawm lub ntsej muag mus rau hauv cov qauv siv lead ua, yog li hloov kev ua haujlwm ntawm lub teeb. Cov cwj pwm yuav luag zoo li ntawm ib qho khoom siv laser ua kom pom.
