Txawm li cas los xij, qhov sib ntxiv ntawm lub ntiaj teb tsis tshua muaj fluorides, xws li yttrium fluoride, tau pom tias txhim kho cov khoom superconducting ntawm MgB2 los ntawm kev nce qhov tseem ceeb tam sim no. ceev thiab txo cov nyhuv ntawm electromagnetic suab nrov.
Lub Ntiaj Teb Tsis tshua muaj fluoride tuaj yeem siv rau hauv kev tsim cov Scintillators?
Synthesis
Lub ntiaj teb tsis tshua muaj fluorides tuaj yeem tsim los ntawm ntau txoj hauv kev, suav nrog cov tshuaj tiv thaiv hauv xeev, cov txheej txheem sol-gel, thiab hydrothermal synthesis. Kev xaiv ntawm txoj kev sib xyaw yog nyob ntawm qhov xav tau ntawm cov tshuaj fluoride thiab daim ntawv thov npaj.
Crystal qauv
Tsis tshua muaj lub ntiaj teb fluorides nthuav tawm ntau yam ntawm cov qauv siv lead ua, nyob ntawm seb muaj pes tsawg leeg thiab cov khoom sib txuas. Qee cov qauv no, xws li cov qauv fluorite, tshwj xeeb tshaj yog zoo rau kev siv hauv cov ntawv thov scintillator vim lawv cov ionic conductivity siab thiab qis lattice zog.
Optical zog
Lub ntiaj teb tsis tshua muaj fluorides nthuav tawm cov khoom siv kho qhov muag, suav nrog kev ua haujlwm siab luminescence, lub neej ntev fluorescence, thiab dav emission spectra. Cov khoom no ua rau lawv tsim nyog siv rau hauv daim ntawv thov scintillator, qhov uas lawv tuaj yeem txhim kho qhov kev tshawb pom rhiab heev thiab txhim kho cov duab ua haujlwm.
Kev hloov hluav taws xob
Lub ntiaj teb tsis tshua muaj fluorides tuaj yeem dhau los ua cov txheej txheem hloov hluav taws xob, uas tso cai rau lawv hloov hluav taws xob hluav taws xob ntau rau hauv lub teeb qis zog. Cov cuab yeej no ua rau lawv tsim nyog siv rau hauv daim ntawv thov scintillator, qhov chaw lawv tuaj yeem ntes thiab duab hluav taws xob hluav taws xob, xws li x-rays thiab gamma rays.
Peb lub Hoobkas
Founded hauv 1958, Hunan Rare Earth Metal Materials Research Institute Co., Ltd. (HNRE), yav tas los hu ua Hunan Metallurgical Research Institute, yog ib qho ntawm thawj ob lub tsev kawm ntawv hauv Suav teb koom nrog hauv lub ntiaj teb tsis tshua muaj smelting, sib cais thiab kev tshawb fawb. HNRE yog lub tsev dai kom zoo nkauj tsim los ntawm Tuam Tshoj txoj haujlwm "ob lub foob pob thiab ib lub satellite" thiab lub teb chaws technological innovation ua qauv qhia kev lag luam.
