AB  - The development of graphene-based materials for optical limiting functionality is 
      an active field of research. Optical limiting for femtosecond laser pulses in the 
      infrared-B (IR-B) (1.4-3 mum) spectral domain has been investigated to a lesser 
      extent than that for nanosecond, picosecond and femtosecond laser pulses at 
      wavelengths up to 1.1 mum. Novel nonlinear optical materials, glassy graphene 
      oxide (GO)-based silico-phosphate composites, were prepared, for the first time 
      to our knowledge, by a convenient and low cost sol-gel method, as described in 
      the paper, using tetraethyl orthosilicate (TEOS), H(3)PO(4) and GO/reduced GO 
      (rGO) as precursors. The characterisation of the GO/rGO silico-phosphate 
      composite films was performed by spectroscopy (Fourier-transform infrared (FTIR), 
      Ultraviolet-Visible-Near Infrared (UV-VIS-NIR) and Raman) and microscopy (atomic 
      force microscopy (AFM) and scanning electron microscope (SEM)) techniques. 
      H(3)PO(4) was found to reduce the rGO dispersed in the precursor's solution with 
      the formation of vertically agglomerated rGO sheets, uniformly distributed on the 
      substrate surface. The capability of these novel graphene oxide-based materials 
      for the optical limiting of femtosecond laser pulses at 1550 nm wavelength was 
      demonstrated by intensity-scan experiments. The GO or rGO presence in the film, 
      their concentrations, the composite films glassy matrix, and the film substrate 
      influence the optical limiting performance of these novel materials and are 
      discussed accordingly.
