    • A process for fabricating a pixelized phosphor having a space between the pixels in the range of about 0.5-25 microns, the process comprising the steps of:(a) depositing a phosphor on a support;(b) exposing the deposited phosphor to a source of electromagnetic radiation through a mask thereby ablating the phosphor segmentally, resulting in a series of structures in both said X and Y directions to produce an array of pixelized phosphors separated by slots;(c) filling the resulting slots between the pixelized phosphors with phosphor material of the same or different composition as utilized in step (a) such that each of the pixelized phosphors on the support are separated by a width of from about 0.5-25 microns; and(d) optionally, planarizing the pixelized phosphors.
    • 一种用于制造像素化磷光体的方法,所述像素化磷光体在所述像素之间具有在约0.5-25微米范围内的空间,所述方法包括以下步骤:(a)在支撑体上沉积磷光体; (b)通过掩模将沉积的磷光体暴露于电磁辐射源,从而分段地消融荧光粉,从而在所述X和Y方向上产生一系列结构,以产生由槽间隔开的像素化磷光体阵列; (c)在像素化的荧光体之间用所述步骤(a)中使用的相同或不同组成的磷光材料填充所得到的槽,使得载体上的每个像素化磷光体分开约0.5-25微米的宽度; 和(d)任选地,使像素化磷光体平坦化。

    • A process for forming a phosphor comprising the steps of:(a) providing a substrate for deposition and growth of an alkali halide phosphor,(b) forming a patterned surface on the substrate comprising a plurality of mesas, each of the mesas having an incline, a decline, and a horizontal surface, the mesas being separated from one another by horizontal segments of the substrate and wherein:(i) the ratio of the height of each of the mesas to the width of the horizontal segments is in the range of about 1:20 to 1:4;(ii) the ratio of the width of each of the mesas to the width of the horizontal segments is in the ratio of about 1:30 to 1:4; and(iii) the angles of incline and decline of each of the mesas are between about 5.degree. to 85.degree.; and(c) depositing an alkali halide phosphor on the patterned surface of the substrate of step (b), thereby forming cracks, in the deposited phosphor, originating from the inclines and/or declines of each of the mesas.
    • 一种用于形成荧光体的方法,包括以下步骤:(a)提供用于碱金属卤化物荧光体的沉积和生长的衬底,(b)在包括多个台面的衬底上形成图案化表面,每个台面具有倾斜 ,下降和水平表面,所述台面通过所述基底的水平段彼此分离,并且其中:(i)每个所述台面的高度与所述水平段的宽度的比率在 约1:20至1:4; (ii)每个台面的宽度与水平段的宽度的比率为约1:30至1:4; 和(iii)每个台面的倾斜角度和下降角在约5°至85°之间; 和(c)在步骤(b)的基板的图案化表面上沉积碱金属卤化物荧光体,从而在沉积的磷光体中形成源于每个台面的倾斜和/或下降的裂纹。
