Abstract

Óxido de zinco dopado com gálio (ZnO:Ga) foi preparado pelo método Pechini a partir de citrato de zinco e hidróxido de gálio. Utilizsando este método, foi possível obter ZnO:Ga cristalino pela calcinação do precursor polimérico em ar a 900ºC por 4 horas. A resina homogênea contendo 2% de dopante só pôde ser obtida com a adição de ácido etilenodiaminotetracético (edta). A adição do edta, também, ocasionou a diminuição de tamanho de partícula do óxido.
