(1)--------------------------- violet vial ( smallest one)
(2) -------------------------- blue vial
(3) --------------------------- green vial
(4) --------------------------- yellow vial
(5) ---------------------------- red vial (largest one)
from violet vial ( smallest in size ) to red vial (largest in size) the energy gap between conduction band and valance band decreases as a result wave length of the emitted light ( or color) increases
