摘要:
Al(3+)-doped ZnO nanocrystals were differently obtained by wet chemical and an electrochemical route. An increase in forbidden gap due to change in crystal size and also due to Al(3+) doping in ZnO is critically analyzed. The Moss-Burstein type shift in Al(3+)-doped ZnO nanocrystals provides an evidence of successful Al(3+) doping in ZnO nanocrystals. The possibility of varying the carrier concentration in ZnO nanocrystals is the indirect implication of the present investigations.
