ntụpọ quantum na ihe mkpuchi ahụ
Dị ka ihe nano akwụkwọ akụkọ, ntụpọ quantum (QDs) nwere arụmọrụ pụtara ìhè n'ihi oke nha ya.Ọdịdị nke ihe a bụ okirikiri ma ọ bụ quasi-spherical, na dayameta ya sitere na 2nm ruo 20nm.QD nwere ọtụtụ uru, dị ka ụdị mkpali dị ukwuu, ụdị ikuku dị warara, nnukwu mmegharị nke Stokes, ogologo oge ndụ fluorescent na ezigbo biocompatibility, ọkachasị ụdị ikuku QD nwere ike kpuchie oke ọkụ niile a na-ahụ anya site na ịgbanwe nha ya.
N'ime ihe dị iche iche QD luminescent, Ⅱ~Ⅵ QDs gụnyere CdSe etinyere na ngwa ngwa n'ihi mmepe ngwa ngwa ha.Obosara nke ọkara elu nke Ⅱ~Ⅵ QDs sitere na 30nm ruo 50nm, nke nwere ike ịdị ala karịa 30nm na ọnọdụ nhazi kwesịrị ekwesị, na mkpụrụ nke fluorescence quantum nke ha fọrọ nke nta ka ọ rute 100%.Agbanyeghị, ọnụnọ CD kpachiri mmepe nke QD.Emepụtara Ⅲ~Ⅴ QD nke na-enweghị Cd nke ukwuu, mkpụrụ nke fluorescence quantum nke ihe a bụ ihe dịka 70%.Ọkara elu obosara nke ìhè akwụkwọ ndụ akwụkwọ ndụ InP/ZnS bụ 40 ~ 50 nm, na ọkụ uhie InP/ZnS bụ ihe dịka 55 nm.Ihe onwunwe nke ihe a kwesịrị imeziwanye ya.N'oge na-adịbeghị anya, ABX3 perovskites nke na-ekwesịghị ikpuchi ihe owuwu shei adọtala ọtụtụ anya.Enwere ike idozi ogologo ikuku ikuku n'ime ọkụ a na-ahụ anya n'ụzọ dị mfe.Mkpụrụ nke fluorescence quantum nke perovskite karịrị 90%, na ọkara elu obosara bụ ihe dịka 15nm.N'ihi agba gamut nke QDs luminescent ihe nwere ike ruo 140% NTSC, ụdị ihe a nwere nnukwu ngwa na ngwaọrụ luminescent.Ngwa ndị bụ isi gụnyere na kama phosphor ụwa na-adịghị ahụkebe na-ebunye ọkụ nke nwere ọtụtụ agba na ọkụ na electrodes dị mkpa.
QD na-egosi agba ọkụ juru eju n'ihi ihe a nwere ike nweta ụdịdị dị iche iche n'ogologo ebili mmiri ọ bụla na mpaghara ọkụ, nke ọkara obosara nke ogologo ebili mmiri dị ala karịa 20nm.Ndị QD nwere ọtụtụ njiri mara, nke gụnyere agba na-emegharị emegharị, ụdị ikuku ikuku dị warara, mkpụrụ nke fluorescence dị elu.Enwere ike iji ha na-ebuli ụdịdị dị iche iche na azụ azụ LCD ma melite ike ngosipụta agba na gamut nke LCD.
Ụzọ mkpuchi nke QD bụ ndị a:
1) On-chip: a na-eji QDs ihe na-egbuke egbuke dochie ntụ ntụ fluorescent omenala, nke bụ isi ihe mkpuchi nke QDs na mpaghara ọkụ.Uru nke a na mgbawa bụ ole na ole nke ihe, na mwepu bụ ihe ga-enwe nnukwu nkwụsi ike.
2) On-elu: Ọdịdị na-bụ-eji na backlight.Ihe nkiri anya bụ nke QD, nke dị n'elu LGP na BLU.Otú ọ dị, ọnụ ahịa dị elu nke nnukwu ebe ihe nkiri ihe nkiri na-ejedebe ọtụtụ ngwa nke usoro a.
3) N'akụkụ: a na-etinye ihe QDs ka ọ bụrụ nkewa, ma tinye ya n'akụkụ eriri LED na LGP.Usoro a belatara mmetụta nke thermal and optical radieshon nke a na-akpata site na-acha anụnụ anụnụ LED na QDs luminescent ihe.Ọzọkwa, oriri nke ihe QD na-ebelatakwa.
