AB  - A simple co-precipitation method has been used for the synthesis of Co(2+) and 
      Ni(2+)-doped zinc borate nanopowders. X-ray diffraction (XRD), Fourier transform 
      infrared (FT-IR), UV/Vis absorption, Scanning electron microscope (SEM) with EDS 
      and photoluminescence (PL) spectroscopies techniques has been employed for their 
      characterization. Powder X-ray diffraction data reveals that the crystal 
      structure belongs to monoclinic for both as-prepared samples. SEM images showed 
      surface morphology of the prepared samples. Optical absorption spectra showed the 
      characteristic bands of doped ions in octahedral site symmetry. From the optical 
      absorption data crystal field and inter-electronic repulsion parameters are 
      evaluated. The FT-IR spectra showed the characteristic vibrational bands related 
      to ZnO, BO3 and BO4 molecules. Photoluminescence spectra exhibited the emission 
      bands in ultraviolet and blue regions.
