| 简介 |
The present invention relates to a nitride phosphor represented by general formula (1), in which the x value of the luminescent color coordinates is less than 0.43 when the nitride phosphor is excited by 455 nm excitation light, and the reflectance of the nitride phosphor at 770 nm is at least 89%. (1) : LnxSiyNn : Z (In the formula, Ln is a rare-earth element that is not an element used as an activator, Z is an activator, x satisfies the expression 2.7 ≤ x ≤ 3.3, y satisfies the expression 5.4 ≤ y ≤ 6.6, and n satisfies the expression 10 ≤ n ≤ 12. |
