iindaba

I-Upconversion luminescence, oko kukuthi, i-anti-Stokes luminescence, ithetha ukuba imathiriyeli ivuyiswa kukukhanya okuphantsi kwamandla kwaye ikhupha ukukhanya kwamandla aphezulu, oko kukuthi, i-material ikhupha ubude obufutshane kunye nokukhanya okuphezulu okuvuyiswa bubude obude kunye nokukhanya okuphantsi.

Ukuguqulwa kwe luminescence
Ngokomthetho kaStokes, izinto eziphathekayo zinokuvuyiswa kuphela kukukhanya kwamandla aphezulu kwaye zikhuphe ukukhanya okuphantsi kwamandla.Ngamanye amazwi, imathiriyeli inokukhupha ubude obubude bezavevele kunye nokukhanya okuphantsi kwamaza ombane xa ichulumanciswa bubude obufutshane bobude kunye nokukhanya okuhamba rhoqo.
Ngokuchasene noko, i-upconversion luminescence ibhekiselele kwizinto ezivuyiswa kukukhanya okunamandla aphantsi kwaye zikhupha ukukhanya ngamandla aphezulu.Ngamanye amazwi, i-material ikhupha ukukhanya kunye ne-wavelength emfutshane kunye ne-frequency ephezulu xa ivuyiswa kukukhanya kunye nobude obude kunye ne-frequency ephantsi.

Umhleli wesicelo seMathiriyeli
Isetyenziswa kakhulu ekubhaqweni kwe-infrared yokukhanya okubonakalayo okukhutshwa sisibane sokukhanya kwe-infrared, iziphawuli zebhayoloji, iimpawu ezilumkisayo ezinokukhanya okude, iimpawu zendlela yomlilo okanye ukupeyintwa kodonga lwangaphakathi njengokukhanya kwasebusuku, njl.
Izinto zokuguqulwa zingasetyenziselwa i-biomonitoring, unyango lweziyobisi, i-CT, i-MRI kunye nezinye iimpawu
