The Types segment classifies Cs2LiYCl6:Ce Crystals into Single‑Crystal, Polycrystalline, Doped‑Variant, and Composite forms. Single‑crystal units, grown by the Czochralski method, provide the highest optical uniformity and dominate high‑performance detector markets, especially in medical imaging, influencing roughly 55 % of the total volume. Polycrystalline aggregates, produced via sintering, offer lower cost and are favored in industrial radiography where absolute resolution is less critical, contributing about 25 % of sales. Doped‑variant crystals adjust cerium concentration (e.g., 0.5 % vs 1 % Ce) to tailor decay times and light output; this customization is essential for high‑energy physics applications, representing 15 % of the market. Composite structures embed Cs2LiYCl6:Ce particles within polymer matrices to improve mechanical robustness for security scanners, accounting for the remaining 5 %. Each type’s price‑performance profile directly impacts its share of the overall market, reinforcing the nuanced market taxonomy.
