We have studied some novel synthesis approach, such as solvothermal synthesis, ionthermal synthesis, synthetic method at low-heating temperatures. So far, three methods have been used to synthesise HEOs, namely solid-state reaction, wet chemical, and epitaxial growth. The wet chemical methods used for synthesizing HEOs include nebulised spray pyrolysis, flame spray pyrolysis and reverse co-precipitation. The third HEC synthesis routine is epitaxial growth of films. So far in the literature only pulsed laser deposition (PLD) has been used to prepare HEOs . However, the cost-effective and large-scale synthesis of high-purity and small-size HEOs is still difficult. Therefore, it is still a challenge for the scientific community to develop an advanced method to prepare HEOs at low temperature.

研究了溶剂热合成、离子热合成、低温合成等新的合成方法。到目前为止，已经有三种方法用于合成HEOS，即固态反应、湿化学和外延生长。湿化学方法主要有喷雾热解法、火焰喷雾热解法和反向共沉淀法。第三个HEC合成程序是外延生长的薄膜。到目前为止，文献中只有脉冲激光沉积（pld）被用来制备heos。然而，高纯度、小尺寸heos的大规模、高成本合成仍然是一个难题。因此，开发一种先进的低温制备heos的方法仍然是科学界面临的挑战。<br>
