摘要

摘要本文报道了通过共沉淀法合成的钙钛矿型锆酸铜纳米颗粒的相演变。XRD研究证实，在700°C下，主要的正交CuZrO3相以及脆弱的四方ZrO2和单斜CuO相形成。XRD分析证实，在700°C退火的样品中存在正交钙钛矿型CuZrO3，电池参数为：a = 6.4552Å, b = 7.4008Å, 和c = 8.4013Å 其晶粒尺寸为54nm。较高的煅烧温度（高于700°C）会导致CuZrO3相中的结晶度下降。XPS研究证实了在700°C退火的样品中存在的组成元素的化学状态。分别使用FTIR和UV-Vis-NIR光谱对样品的化学键合和光学特性进行了探测。在不同温度下退火的合成样品的光学带隙能量范围为3.36–3.08eV。

Temperature-mediated phase evolution of perovskite-type CuZrO3 nanoparticles

ABSTRACT Herein, we report the phase evolution of perovskite-type copper zirconate nanoparticles synthesized via the coprecipitation method. The XRD investigations confirm the dominant orthorhombic CuZrO3 phase formation at 700 °C along with frail tetragonal ZrO2 and monoclinic CuO phases. XRD analysis confirms the presence of orthorhombic perovskite type CuZrO3 in the sample annealed at 700 °C with cell parameters: a = 6.4552 Å, b = 7.4008 Å, and c = 8.4013 Å whose crystallite sizes is 54 nm. Higher calcination temperatures (above 700 °C) induce the crystallinity deterioration in the CuZrO3 phase. The XPS studies substantiate the chemical state of constituent elements present in the sample annealed at 700 °C. The chemical bonding and optical features of the samples were probed using FTIR and UV-Vis-NIR spectroscopy, respectively. The optical bandgap energies for the synthesized samples that were annealed at various temperatures ranged from 3.36–3.08 eV.

期刊介绍： Phase Transitions is the only journal devoted exclusively to this important subject. It provides a focus for papers on most aspects of phase transitions in condensed matter. Although emphasis is placed primarily on experimental work, theoretical papers are welcome if they have some bearing on experimental results. The areas of interest include: -structural phase transitions (ferroelectric, ferroelastic, multiferroic, order-disorder, Jahn-Teller, etc.) under a range of external parameters (temperature, pressure, strain, electric/magnetic fields, etc.) -geophysical phase transitions -metal-insulator phase transitions -superconducting and superfluid transitions -magnetic phase transitions -critical phenomena and physical properties at phase transitions -liquid crystals -technological applications of phase transitions -quantum phase transitions Phase Transitions publishes both research papers and invited articles devoted to special topics. Major review papers are particularly welcome. A further emphasis of the journal is the publication of a selected number of small workshops, which are at the forefront of their field.
