Claim 0:
1. A method of selectively growing crystals, comprising:
selecting a precursor solution for crystals growth,
applying the selected precursor solution onto a substrate with pre-nucleated crystal seeds;
changing the precursor concentration to selectively associate with size of nucleating material seeds, wherein the concentration is inversely proportional to initial crystal size of the nucleated material seed, wherein the concentration varies between 6.16 to 27.10 mM associating in diameter of the initial crystal size varies between 1150 nm to 280 nm; and
irradiating the pre-nucleated crystal seeds on the substrate through the precursor by a pulsed laser with a predetermined input energy, thereby growing crystal on the substrate and controlling nanocrystals' features of orientation, wherein the precursor solution contains precursor reactants of zinc chloride and hexamethylene tetramine (HMTA) with a content ratio of the precursor reactants zinc chloride and HMTA of 1:1.
