Hawthorn (Crataegus pinnatifida Bge.) contains various active components including polysaccharides, polyphenols, vitamin, phenolic acid, etc. Polysaccharides are one of the most critical active components in hawthorn, which exhibits different biological activities such as immunomodulatory antioxidant, anti‐inflammatory, hypoglycemic, and other activities. Hence, the main purpose of this paper is to...
Bi 3+ , Sm 3+ co-doped La 0.99−x Bi x Sm 0.01 PO 4 polycrystalline samples were synthesized by calcining precursors at 800°C in air. The precursors were obtained via low-heating temperature solid-state reactions. Crystal structures of the phosphor were examined with XRD and a pure phase was confirmed. The excitation spectra show that the phosphor can...
