Structural properties of SnO₂ films dopped by Lithium

الملخص

This paper the undoped Tin Oxide( SnO₂) and Lithium doped( SnO₂:Li) were prepared with doping percentage (5%) for the Molartiy (0.05, 0.1 , 0.15 , 0.2 ) ,were prepared by using chemical Spray pyrolysis technique (CSP) . Have been deposited on a glass substrate temperature at (400℃) , And the thickness of the prepared films were (350∓15) nm . By the X-Ray diffraction technique the nature of structure was exmined with aprefered orientation along (110) . It was found that . The prepared undoped ( SnO₂) and indoped( SnO₂) have a (Tetragonal) polycrystalline structure . Also it was found that the average crystalline size increase as the increase in doping of the concentration(9.20 – 21.86) nm . AFM images the average grain size increase of the Molarity (73.60 -106.16)nm.
