Upconverting luminescent cov khoom
Cov ntaub ntawv hloov kho luminescent yog cov khoom siv luminescent uas nqus cov hluav taws xob tsawg lub teeb hluav taws xob thiab tawm hluav taws xob lub teeb hluav taws xob loj. Up-hloov luminescence hais txog qhov tshwm sim uas ob lossis ntau qhov qis zog hluav taws xob photon tau hloov pauv mus rau hauv ib lub siab photon. Lub luminescence mechanism ntawm up-conversion luminescent cov ntaub ntawv yog vim qhov txuas txuas nyhuv ntawm ob-photon lossis multi-photon; nws cov xeeb ceem yog tias lub zog ntawm lub nqus photon tsawg dua lub zog ntawm lub tshuab emon photon. Qhov tshwm sim no txhaum txoj cai Stokes, yog li hom khoom siv no tseem hu ua anti-Stokes luminescent khoom. Hauv qee cov ntaub ntawv, kho dua tshiab luminescent cov ntaub ntawv tshwj xeeb xa mus rau cov ntaub ntawv uas hloov tawm infrared teeb mus rau hauv lub teeb pom kev.
