Muna 2019, Sung Jun Park et al. Syntheshised YBO3: LN3 + (LN = EU, TB) phosphors kuburikidza nenzira inokonzeresa mari yekuona zvigunwe uye kuderedza nzira yekumashure. Muna 2020, prabakaran et al. Yakagadzirwa fluorescent na [eU (5,50 dMBp) 3] 3] 3] 3] · CL3 Na [EU (5,5 '- DMBP) (PHEN) 3] 3 / D-D-DEXTRose Complex. Kuburikidza nekuedzwa, iyo manyoro inogona kuratidza zvakajeka zvigunwe pazvinhu zvakadai sepapurasitiki emapurasitiki ematanda, uye magirazi eSouth Africa pasi pechiedza chezuva Muna 2021, Dan Zhang et al. Yakabudiriragadzirwa zvakagadzirwa uye zvakanyatsogadzirwa uye yakaoma eu6 Nekudaro, kumwe kuongororwa kunodiwa kuti uone kuti yakakodzera yevaeni yevaeni. Muna 2022, l Brini et al. zvinobudirira Synthesised EU: Y2SN2O7 Fluorescent Poda Nzira yekunyora Under 254nm Ultraviolet kufadza uye yakajeka girini fluorescence pasi pe988nm padyo-infrared kufarirwa, kuwana dual mode kuratidzwa kweminwe yeminwe kune iyo yeminwe. Chinogona kuitika zvigunwe zvezvinhu zvakaita seCeramic mataira, masheya epurasitiki, rombo, uye sarudzo, kusiyanisa, kusiyana, uye kuramba kwakasimba kwekukanganiswa.

Mumakore achangopfuura, kutsvagisaRare Pasi EurtopuumComplexes yakakwezva kutarisisa zvakanyanya, nekuda kwezvivakwa zvavo zvakanakisa uye zvemagineti zvakakwirira zvekunyanyisa Nekunonoka kwekutsvagisa pane zvisingawanzogadzirwa zvepasi zvivakwa zvepasi, zvavakaita munzvimbo dzakasiyana siyana sekuvhenekera uye kuratidzwa, kurapa kweruzivo, kuwanda kwekunyepedzera, kuwanda kwekunyepedzera. Iyo Optical Properties yeEuropiumComplexes yakanaka kwazvo, uye minda yavo yekunyorera inowedzera zvishoma nezvishoma. Nekudaro, kushaya kwavo kwekunyora kwekunyora, manhamba ekugadzira, uye maitiro ekugadzira anozadzisa zvavanoshandisa zvinoshanda. Kubva pane yazvino yekutsvaga maonero, kutsvagisa kwekushandisa kweiyo Optical Properties yeEuropiumComplexes mumunda wenyaya yesainzi yesainzi inofanira kunyanya kutarisa pane kuvandudza iyo Optical Properties yeEuropiumkuomesa uye kugadzirisa matambudziko ezvinyorwa zveFluorescent kuve nekukasira kuunganidzwa munzvimbo dzakanyorova, kuchengeta kugadzikana uye luminescence yekubudirira kweEuropiumyakaoma mumvura mhinduro. Mazuva ano, kufambira mberi kwenharaunda uye sainzi uye tekinoroji zvakaisa mberi zvinodiwa zvakakwirira zvekugadzirira zvinhu zvitsva. Paunenge uchisangana application zvido, zvinofanirwawo kutevedzera maitiro emugadziro wakashata uye mutengo wakaderera. Naizvozvo, zvakare nekutsvagisaEuropiumComplexes ndeye yakakosha kukosha kwekuvandudzwa kweiyo yakapfuma yeChina isingaore pasi zviwanikwa uye kukura kwetsotsi sainzi uye tekinoroji.
