Y{sub 2}O{sub 3} sheets, rods, needles and tubes were synthesized from three precursors through hydrothermal reactions followed by calcination. The phase distribution and decomposition behaviors of the three precursors, Y{sub 2}(OH){sub 5.14}(NO{sub 3}){sub 0.86}.H{sub 2}O, Y{sub 4}O(OH){sub 9}(NO{sub 3}) and hexagonal Y(OH){sub 3}, were investigated. The reaction temperature and initial pH value during the hydrothermal reaction showed great influence on the shape and particle size of the products. The precursors were converted to Y{sub 2}O{sub 3} particles with the retained original morphology of the precursors. - Graphical abstract: Y{sub 2}O{sub 3} particles in the shape of sheet, rod, needle and tube with controlled size were synthesized from three precursors, Y{sub 2}(OH){sub 5.14}(NO{sub 3}){sub 0.86}.H{sub 2}O, Y{sub 4}O(OH){sub 9}(NO{sub 3}) and hexagonal Y(OH){sub 3}, obtained by hydrothermal reactions with controlled pH value and reaction temperature.
