Nov yog qee cov ntsiab lus ntxiv txog cov xim fluorescent thiab xim luminous:
Fluorescent xim:
Cov xim fluorescent siv hauv cov xim fluorescent muaj cov khoom sib txuas hu ua fluorescent dyes lossis chromophores.
Cov dyes muaj peev xwm nqus tau lub zog siab UV lub teeb (tsis pom ntawm tib neeg lub qhov muag) thiab hloov mus rau hauv qis-zog pom lub teeb.
Lub teeb absorbed UV excites cov electrons nyob rau hauv cov xim molecules, uas ces emit lub teeb ntawm ntev wavelengths nyob rau hauv lub pom spectrum.
Cov xim fluorescent muaj nyob rau hauv ntau yam xim, nrog rau cov xim daj, txiv kab ntxwv, paj yeeb, thiab ntsuab, uas tshwm sim heev saturated thiab khaus nyob rau hauv ib txwm tsaus ntuj.
Lawv tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov ntawv thov uas pom kev thiab saib xyuas yog qhov tseem ceeb, xws li kev ceeb toom kev nyab xeeb, cov paib tsheb, cov khoom ua si, thiab cov haujlwm ua yeeb yam.
Cov nyhuv fluorescent ntawm cov xim no tau tshaj tawm nyob rau hauv qhov chaw teeb pom kev UV, xws li cov teeb dub lossis cov teeb ci ultraviolet.
Luminous Paint (Glow-in-the-Dark Paint):
Luminous pigments siv nyob rau hauv glow-in-the-dub xim muaj phosphors, uas yog cov khoom uas muaj phosphorescence.
Phosphorescence yog qhov tshwm sim uas cov khoom siv absorbs lub teeb lub zog thiab maj mam tso nws mus rau lub sijhawm ntev.
Thaum raug lub teeb, cov phosphors nyob rau hauv cov xim luminous ua zoo siab thiab khaws lub zog.
Thaum tsis muaj lub teeb, lub zog khaws cia maj mam tso tawm raws li pom lub teeb, uas ua rau lub teeb ci lossis luminescent.
Cov xim luminous feem ntau yog tsim los ntawm cov khoom siv khi uas tuav cov phosphorescent pigments ua ke thiab tso cai rau lawv siv los ua txheej txheej.
Cov nyhuv ci ntsa iab ntawm cov xim pleev xim zoo li yuav pom ntau dua nyob rau hauv qhov tsaus ntuj lossis qhov chaw tsis muaj teeb pom kev zoo, vim qhov sib txawv ntawm ib puag ncig ua kom pom kev pom.
Lub sij hawm thiab kev siv ntawm lub ci nyob ntawm seb yam xws li qhov zoo ntawm cov phosphorescent pigments thiab tus nqi ntawm lub teeb rau them.
Ob leeg xim fluorescent thiab luminous xim muaj cov khoom tshwj xeeb thiab siv rau ntau lub hom phiaj raws li lawv cov yam ntxwv ntawm lub teeb-emitting.
