Ka'idar Semiconductor LED yana buƙatar fahimtar

Ana niƙa kristal mai haske-emitting diode Inumgarnet (CE3: yag) a cikin foda kuma a haɗe shi da shi a cikin manne mai yawa. Lokacin da guntu na LED ya fitar da haske mai shuɗi, wasu Blu-ray za a canza su ta wannan crystal tare da kewayon spectral (kimanin 580nm a tsakiyar bakan). (A gaskiya, YAG na kristal guda ɗaya da aka gauraya CE ana ɗaukarsa a matsayin flicker fiye da phosphorus). Kuma ana kiran launinsa sau da yawa “Farin wata ”. Wannan hanyar yin farin haske LED Nichiacorporation ne ya haɓaka kuma ya fara samar da farin farin LED a cikin 1996. Idan kana son ka daidaita launin haske mai fatsa, kana iya yin amfani da wasu ƙarnu marasa ƙasa ko kuma don a sake (CE) da aka haɗa cikin CE3: yag, kuma hanyar sake canja ɓoye ko kuma aluminum a YAG don su yi shi. Dangane da halayen bakan sa, abubuwa ja da kore sun yi ƙasa da na madaidaicin haske mai faɗi ƙarƙashin wannan fiddawar LED. Bugu da ƙari, saboda maye gurbin yanayin samarwa, yanayin zafin launi na wannan ƙãre samfurin ba daidai ba ne, daga rawaya mai dumi zuwa launin shuɗi mai sanyi. Saboda haka, a cikin tsarin samarwa. Wata hanyar LED mai launin fari-haske kamar fitila mai kyalli. LED ɗin da ke fitar da kusan hasken ultraviolet za a fentin shi da gaurayawar phosphorus guda biyu, ɗaya ja da haske mai shuɗi, ɗayan kuma hasken kore ne. Copper da aluminum tare da zinc sulfide (ZNS). Duk da haka, saboda hasken ultraviolet na iya yin fashewar resin epoxy da tabarbarewar adhesives, samarwa ya fi wahala kuma tsawon rai yana da gajere. Idan aka kwatanta da hanyar farko, yana da ƙarancin inganci kuma yana samar da ƙarin zafi (saboda tsohon STOKESSHIFT yana da babban tsohon), amma fa'idar ita ce halaye na bakan sun fi kyau. Saboda ikon LED na hasken UV yana da girma, kodayake ingancin ya yi ƙasa kaɗan, hasken yana fitowa yana kama da haka. Sabuwar hanyar yin farin haske LEDs baya amfani da jikin hasken phosphorus kuma. Sabuwar hanyar ita ce shuka zinc a cikin sinadarin zinc-zinc (ZNSE). Lokacin da aka kunna ta, wurin da yake aiki zai fitar da haske shuɗi kuma substrate ɗin zai zama rawaya, kuma zai zama farin haske don haɗuwa.
