stock solution of 0.8 oxalic acid was prepared by dissolving ox-
alic acid (1.44 g) in deionized water (20mL).

In a typical procedure for the preparation of the products, H3PO3
(0.82 g, 0.01 mol) was dissolved in deionized water (10mL). Lan-
thanum oxalate complexes were prepared by mixing together LaCl3
(20 mL, 0.5 ) and oxalic acid (20 mL, 0.8 ) stock solutions. The
precipitate of lanthanum oxalate was filtered and washed with dis-
tilled water, then added into a solution of H3PO3 and the initial
pH of the solution was adjusted by NaOH to about 12 while stir-
ring. The mixture was stirred for 1 h at room temperature with
the addition of NaCl as mineralizer. After that, the mixture was
transferred into a Teflon-lined stainless steel autoclave with a vol-
ume of 20mL and heated for 5 d at 180°C under autogenous pres-
sure. After cooling, the solids were washed with distilled water, and
once with anhydrous ethanol, and dried overnight at 70°C in air
before further characterization. In order to get the LaPO4, the La-
(HO)(HPO3) phase was calcined for 5 h at 500°C in muffle furnace,
and the structure was confirmed by XRPD.
Characterization: The morphologies of the grown crystals were ex-
amined by an electron probe microanalyzer (EPMA, model JSM-
6700F, JEOL, Japan). Energy dispersive spectroscopy (EDS) data
were recorded with an INCA analyzer having an attachment of an
EPMA (model 8705QH2, Shimadzu, Japan) for carrying out the
elemental analysis of the grown crystals. The IR spectrum was col-
lected with a Digilab-FTS-80 spectrophotometer by using pressed
KBr pellets of the samples. UV luminescence spectra were recorded
with a Shimadyn RF-5301 spectrofluorophotometer at room tem-
perature, and a 450 W xenon lamp was used as an excitation source.
