中文摘要	laco3oh nano/microcrystals with a variety of morphologies/sizes including nanoflakes, microflowers, nano/microrhombuses, two-double microhexagrams sandwichlike microspindles, and peach-nucleus-shaped microcrystals have been synthesized via a facile homogeneous precipitation route under mild conditions. a series of controlled experiments indicate that the ph values in the initial reaction systems, carbon sources, and simple ions (nh4+ and na+) were responsible for the shape determination of the laco3oh products. a possible formation mechanism for these products with diverse architectures has been presented. after annealing at suitable temperatures, leco(3)oh was easily converted to la2o2co3 and la2o3 with the initial morphologies. a systematic study on the photoluminescence and cathodoluminescence properties of eu3+ - or tb3+ - doped la2o2co3/la2o3 samples has been performed in detail. the excitation and site-selective emission spectra were recorded to investigate the microstructure, site symmetry, and difference in the d-5(0)-> f-7(2) transition of eu3+ ions in la2o2co3 and la2o3 host lattices. in addition, the dependence of the luminescent intensity on the morphology for the as-prepared la2o2co3/la2o3:ln(3+) (ln = eu, tb) samples has been investigated. the ability of generating diverse morphologies and multiemitting colors for different rare-earth activator ion (ln eu, tb) doped la2o2co3/la2o3 nano/microstructures provides a great opportunity for the systematic evaluation of morphology-dependent luminescence properties, as well as the full exploration of their application in many types of color display fields.
