A series of experiments have been conducted to examine ball milling parameters, such as
the size of beads, ball milling time, the ratio of beads/phosphor/water, and the material
composition of the ball milling beads to optimize the milling conditions for phosphor
powders. It is concluded that longer time, smaller size of Φ2 Al2O3 beads, and higher ratio
of beads/phosphor/water= 2: 1: 0.5 can produce phosphor powder with higher dispersibility
which in turn creates a densely packed coating of phosphor particles on the screen, a …
