Inkcazo emfutshane:

Iifestile ze-Sapphire optical ziinxalenye ezikhethekileyo ze-optical ezenziwe nge-single-crystal aluminum oxide (Al₂O₃), eyaziwa ngokusebenza kwayo okugqwesileyo kwe-optical, amandla oomatshini, kunye nokuzinza kweekhemikhali. Njenge-oxide crystal enzima kakhulu (ubunzima be-Mohs 9), iifestile ze-sapphire zibonisa ukuhanjiswa okugqwesileyo (~83-85% okungagqunywanga) kwi-ultraviolet (200nm) ukuya kwi-mid-infrared (5.5μm) spectra, nto leyo eyenza ukuba zilungele ukusetyenziswa okufunayo okufuna ukukhanya okuphezulu kunye nokuqina.

Ukuvelisa kubandakanya iinkqubo eziphambili eziquka ukukhula kwe-crystal orientation, ukucocwa ngokuchanekileyo, ukupolisha i-nanoscale, kunye nokufakelwa okukhethekileyo. Iindlela zokukhula eziphambili (umz., iindlela ze-HEM okanye ze-KY) zivelisa ii-boule ezikumgangatho ophezulu ezinobunzima obuphantsi (<10⁴/cm²). Ulwakhiwo lwe-crystal olukhethekileyo olune-hexagonal luvumela iipropati ze-anisotropic, kunye ne-orientations ezilungiselelwe kakuhle (C-axis, A-axis, okanye R-plane cuts) ezilungelelanisa ukusebenza kwe-optical kwizicelo ezithile.
