    abstract = {In the present research, the effect oftitanium nanoparticles 
  on optical properties of (PVA-PVAC) has been studied. For this purpose, many 
  samples were prepared with different weight percentages of titanium nanoparticles, 
  the samples were prepared by casting method. The absorption spectrum has been 
  recorded in the wave length range 200-1100 nm, the optical energy gap of the 
  indirect allowed and forbidden transition, absorption coefficient and optical 
  constants, such as (extinction coefficient, refractive index and real and imaginary 
  dielectric constants) have been determined. The optical constants are increase 
  with increasing of titanium nanoparticles concentration, also the energy gap 
  decreased with increasing the weight percentages of titanium nanoparticle.}
