## Abstract Electrical properties of Er‐doped SnO~2~ thin films obtained by sol‐gel‐dip‐coating technique were measured. When compared to undoped tin dioxide, rare‐earth doped films present much higher resistivity, indicating that Er^3+^ presents an acceptor–like character into the matrix, which le
