Reply to the Comments on “Synthesis and Structural Characterization of Rutile SnO₂ Nanocrystals” by Z. Chen, J.K.L. Lai, C.H. Shek, and H. Chen [J. Mater. Res. 18, 1289 (2003)]

Response to “Comment on ‘Facile strategy and mechanism for orthorhombic SnO2 thin films’” [Appl. Phys. Lett. 94, 186103 (2009)]

“…1 of our paper 4 shows the presence of a significant amount of the amorphous phase. Typical x-ray diffraction spectra of the amorphous phase show a broad convex shape, 5,6 which are very different from that reported in Fig. 1 of our paper.…”

Preparation and characterization of high specific surface area Mn3O4 from electrolytic manganese residue

“…(MOCVD) [20], sol-gel process with KMnO 4 and fumaric acid at high temperature, and sonochemical reaction of Mn(CH 3 COO) 2 with NaOH or etramethylammonium hydroxide (TMAH) [21], surfactant-assisted methods [22] have also been reported. While these methods have provided nanomaterials for fundamental studies, they are obviously not suitable for industrial applications.…”

“…2͔, characteristic of Sn 4+ in an amorphous environment, 7 and ͑c͒ the broadness of features in the XANES spectrum compared with the crystalline reference sample. 8 Related studies, 1,3-5,9-11 including one from the same authors, 5 show that films deposited using PLD in vacuum or at low oxygen pressures contain an amorphous phase. We note that crystalline rutile-SnO 2 films have been obtained using PLD under an oxygen atmosphere; 9-11 however, at much higher oxygen pressures ͑i.e., tens of pascal͒ than used in this study.…”

“…[12][13][14] In a recent reply 14 to a comment 13 made on an earlier paper of theirs, 12 they conclude that: "In general, for pulsed laser deposition of SnO 2 thin films grown under room temperature, the amorphous phase is ineluctable." We agree and conclude that the film reported in Ref.…”
