摘要：
As one of purposes, the present invention provides: a single-crystal phosphor which can exhibit excellent properties under high-temperature conditions; and a light-emitting device in which the phosphor is used. As one embodiment, a single-crystal phosphor is provided, which has a chemical composition represented by the compositional formula: (Y 1-x-y-z Lu x Gd y Ce z ) 3+a Al 5-a O 12 ( 0 ≤ x ≤ 0.9994 , 0 ≤ y ≤ 0.0669 , 0.0002 ≤ z ≤ 0.0067 , -0.016 ≤ a ≤ 0.315 ).
