  The band gap energies of SnO_2 nanoparticles are calculated to be about 3.91-3.98 eV from the diffuse reflectance spectrum (DRS). The Urbach energies are found to be increasing from 0.219 to 0.46 eV with the decrease of annealing temperature.3.

  2.通过紫外-可见-近红外分光光度计测试样品的漫反射,计算得到禁带宽度大约为3.91-3.98 eV,并且发现随着退火温度的降低,Urbach能量从0.219增大到0.46 eV。
