Abstract
The growth of a phosphor layer deposited on a patterned substrate containing a multiplicity of recessed ridges of triangular cross section can be controlled by tailoring the geometry of the recessed ridge structures. During the deposition process, little or no phosphor deposition occurs on the recessed ridge structures, and cracks are formed which separate the otherwise uniformly growing phosphor which is present in other regions of the patterned substrate where more substantial phosphor deposition occurs.
