Plasmons yog kev sib sau ua ke ntawm cov hluav taws xob dawb hauv cov hlauuas, thaum txhawb los ntawm lub zog xws li hnub ci lossis laser, teeb tsa kev sib haum xeeb ntawm cov nqi saum npoo zoo ib yam li nthwv dej. … "Lub plasmon tsim hluav taws xob kub uas lwj sai heev, yog li cuam tshuam lawv yog qhov nyuaj," nws hais.
Plasmons tsim tawm li cas hauv txoj kev SPR?
SPR tshwm sim thaum polarized lub teeb tawm tsam cov hluav taws xob ua hluav taws xob ntawm qhov sib cuam tshuam ntawm ob lub xov xwmQhov no tsim hluav taws xob hluav taws xob ceev nthwv dej hu ua plasmons, txo qhov kev siv ntawm lub teeb pom kev ntawm ib lub kaum ntse ntse. lub npe hu ua lub resonance lub kaum ntse ntse, nyob rau hauv kev faib ua feem rau qhov loj ntawm ib tug sensor nto.
Plasmons hauv chemistry yog dab tsi?
Plasmons yog sib sau ua ke ntawm cov electrons uas muaj nyob rau ntawm qhov loj thiab qhov chaw ntawm cov khoom sivthiab nyob hauv ib puag ncig ntawm kev ua cov khoom.
Plasmons hauv lub xeev physics yog dab tsi?
1 Plasmons yog dab tsi? Raws li cov tshuaj tiv thaiv rau kev hloov pauv, cov electrons yuav pib oscillate nrog ωp. Koj tuaj yeem ntsuas cov oscillations thiab qhov tshwm sim quasiparticles hu ua plasmons. Lawv muab lub zog hluav taws xob rau qhov ceev ceev.
Plasmon zog suav li cas?
Lub zog plasmon ntawm qhov sib txuas ntawm cov hlau thiab lub tshuab nqus tsev yog Es=Ep / √2 E s=E p / 2 vim tias qhov dielectric tas li ntawm lub tshuab nqus tsev yog εd=1.
