Zvinoenderana nemutemo weStokes, zvinhu zvinongogona kunakidzwa nemwenje wesimba uye unoburitsa yakaderera simba mwenje.Mune mamwe mazwi, zvinhu zvinogona kuburitsa kureba wavelength uye yakaderera frequency mwenje kana uchinakidzwa nepfupi wavelength uye yakakwirira frequency mwenje.
Pane zvinopesana, upconversion luminescence inoreva zvinhu zvinofadzwa nechiedza chine simba shoma uye chinobudisa chiedza chine simba guru.Mune mamwe mazwi, zvinhu zvinoburitsa mwenje nepfupi wavelength uye yakakwirira frequency kana ichinakidzwa nechiedza chine wavelength refu uye yakaderera frequency.
Kusvika parizvino, upconversion luminescence yakaitika mumisanganiswa yakasanganiswa neasingawanzo pasi ion, kunyanya fluoride, oxide, sulfur makomisheni, fluorine oxides, halides, nezvimwe.
NaYF4 ndiyo substrate zvinhu ine yepamusoro-shanduko yeruminescence kunyatsoshanda.Semuenzaniso, apo NaYF4: Er, Yb, kureva, ytterbium uye erbiumkaviri-doped,Er inoshanda se activator uye Yb se sensitizer.
