CA 2273811
A neon gas discharge lamp is provided which produces an acceptable amber color emission for automotive applications. The red emission from the neon discharge when the lamp is operated in a pulsed mode is combined with a green emission from a substituted Y3A1 15 O 12:Ce phosphor coated on the interior surface of the lamp. The resulting amber emission meets both SAE and ECE amber color requirements. In particular, phosphor has the general formula: Y3-(a+b+c) Ce a B b V c A1 5 O 12 where M is Gd or La; V are lattice vacanies; 0.01 ~ a ~ 0.08; 0.60 ~ b ~ 2.4; and 0 ~ c ~ 0.1
