Orderly patterned remote phosphor crystal material and method for preparation the material and its application

A method for preparing an orderly patterned remote phosphor crystal material, comprising steps of:

• 1) placing a remote phosphor crystal material ready for processing on a stage which is movable freely along 2-dimensionally horizontal directions, and focusing a short-pulse laser on a surface or above the surface of the remote phosphor crystal material ready for processing;
• and
• 2) moving a stage which carries the remote phosphor crystal material and point-by-point scanning the surface of the remote phosphor crystal material with the short-pulse laser, which forms micro-structure arrays on the surface of the remote phosphor crystal material;
• a shape, a size and a spacing of a single structure in the micro-structure arrays is combinedly controlled by a power of a pulsed laser, repetition frequency of the pulse laser, a spacing between a laser focal plane and the surface of the material and a moving speed of the stage;
• wherein the orderly patterned remote phosphor crystal material comprises:
• a remote phosphor crystal material body, the orderly patterned micro-structure arrays on the surface of the remote phosphor crystal material body, which are produced by laser ablation.
