The crystals grown in the strongly reducing medium mentioned above have a high density of F and F + centers, the ratio of which may vary from one sample to another. The neutral F centers are characterized by 6.05 eV absorption bands; those positively charged possess 4.8 and 5.4 eV bands.
Ingot Sapphire is the main substrate material for LED lighting chips. Due to its reasonable cost and performance advantages, it accounts for up to 90% of all kinds of LED lighting substrates. Zhongju is capable of processing substrates according to customer needs. With 100% accurately maked exclusion areas, it allows us to help downstream industry to reduce cutting costs efficiently. Currently, our sapphire ingot productions ranges from 2 to 12 inches with high quality.
