Oxalic acid dihydrate (OADH) crystal was grown by slow evaporation solution method, milled to micro-OADH, impacted with shocked 50 pulses and harvested in a 16-day period. The 2 MPa pressure with 2.2 Mach number of 864 K temperature specifies the product as shocked 50 scaled OADH. Single crystalline X-ray diffraction of OADH macro are as specified with P2 1 /n as space group with monoclinic as the crystal system and shocked 50 scaled OADH are with lattice constants; the % of elements of OADH specimen are confirmed by theory and practice. The dielectric constant of OADH is higher at lower frequency values by space charge polarization. OADH of all scales are of the negative photo-conductivity type. The influx data of OADH of three types of scaling are identified as better electronic filter. The micro-OADH is confirmed by the scanning electron microscopy analysis as 10 micrometer scaling without any flaws. The Fluorescence (FL) study shows bluish FL emission for all samples of OADH; sensitivity is 8.88>6.6>2.2 for shocked 50-OADH, micro-OADH, macro-OADH. The Miller’s indices of (101) profile for RGB display is shown without as well with recursive colors of OADH.
