文摘

Co-precipitation technique is used to synthesize gamma- Al2O3 nanopowders. Pure gamma- Al2O3 phase was obtained having maximum nanoparticle size is 24 nm. The quantum dots were formed inside powder. High surface area of nanopowders at the low annealing temperature. Increasing annealing temperature causes the hexagonal agglomeration shape.
