Ngokomthetho wakwa-Stokes, izinto zokwakha zingajatshuliswa kuphela ukukhanya kwamandla aphezulu futhi zikhiphe ukukhanya okuphansi kwamandla.Ngamanye amazwi, izinto ezisetshenziswayo zingakhipha ubude begagasi ende kanye nokukhanya kwefrikhwensi ephansi uma kujatshulwe ubude begagasi obufushane nokukhanya kwefrikhwensi ephezulu.
Ngokuphambene nalokho, i-upconversion luminescence ibhekisela endabeni ejatshuliswa ukukhanya okunamandla aphansi futhi ikhipha ukukhanya okunamandla aphezulu.Ngamanye amazwi, okokusebenza kukhipha ukukhanya okunobude beza obufushane kanye nemvamisa ephezulu uma kujatshulwe ukukhanya okunobude beza obubude nefrikhwensi ephansi.
Kuze kube manje, i-upconversion luminescence yenzekile kumakhompiyutha ane-ion yomhlaba engavamile, ikakhulukazi i-fluoride, i-oxide, i-sulfur compounds, i-fluorine oxides, i-halides, njll.
I-NaYF4 iyingxenye ye-substrate ene-luminescence ephezulu kakhulu yokuguqulwa kwe-luminescence.Isibonelo, uma i-NaYF4: Er, Yb, okungukuthi, i-ytterbium ne-erbiumi-double doped,I-Er isebenza njengesiqalisi bese u-Yb eyisithulisi.
