Shaybaadhka-Grown Midabka Sapphire-ka Dhagax-dhagaxa ee Magenta ee La Habeeyay & Kiisaska Daawashada

Shaybaadhka-Grown Dhagaxyada Sapphire-ka ee Midabka leh ee Magenta Qurxinta La Habeeyay & Daawo Kiisaska Sifaysan Sawirka

Sharaxaad Gaaban:

Sapphire rough (Magenta hue) ee shaybaadhka leh ayaa lagu farsameeyay iyadoo la isticmaalayo tignoolajiyada horumarsan ee Hydride Vapor Phase Epitaxy (HVPE), iyadoo la gaadhayo sifooyin kiimikaad jireed oo la mid ah sapphire dabiiciga ah. Iyada oo loo marayo xakamaynta saxda ah ee chromium (Cr³⁺: 0.3-0.7wt%) iyo titanium (Ti⁴⁺: 0.05-0.15wt%) fiirsashada xad-dhaafka ah ee la socodka wakhtiga dhabta ah ee Raman spectroscopy, kiriimyadani waxay muujinayaan midabaynta magenta xasilloon (CIE x = 0.35-0.38, 8, 8, 0.38, 2, 2,5 y 610± 5nm, saturation 85±5%). Maaddadu waxay muujinaysaa Mohs 9 adkaanta (Vickers 2200-2300HV), xasilloonida kuleylka aan caadiga ahayn (-200 ° C ilaa 800 ° C iyada oo aan midab lahayn), iyo gudbinta iftiinka sare (> 82% @ 400-700nm). Iyada oo kaamilnimada crystal (ku-jirta <0.001%) dhaaftay dhigeyaasha dabiiciga ah iyo awoodda wax-soo-saarka ee 80mm-daamur-boules (soo saaraya 78%), sapphire-kan la farsameeyay wuxuu u taagan yahay horumar xagga saacadaha raaxada ah, qaybaha hawada hawada, iyo codsiyada indhaha ee quantum.
