Starting from stoichiometric mixtures of lutetium and silicon oxides, Lu₂SiO₅ (LSO) crystals to eutectic ceramic rods were obtained using the laser floating zone (LFZ) technique in air at growth rates ranging from 200 to 5 mm/h. The newly obtained eutectic is formed by Lu₂O₃ fibrils and/or lamellae into a LSO matrix being its formation induced by a SiO₂ evaporation process during the LFZ growth.

Scanning electron microscopy (SEM) and Raman spectroscopy studies allowed observing how growth rate affects microstructural evolution, namely the transition from single crystal to eutectic. SEM observations show that the eutectics present alternated monophasic oxyorthosilicate regions with biphasic Lu₂SiO₅/Lu₂O₃ ones identified by X-Ray diffraction as C2/c monoclinic Lu₂SiO₅ and Ia${\displaystyle \overline{3}}$ cubic lutetium oxide.

While the luminescence phenomena were found to be only dependent on the excitation energy, a pronounced UV light-induced reversible photochromic effect was observed in the samples grown at slower rates.

从of和氧化硅的化学计量混合物开始，使用激光浮区（LFZ）技术在空气中以200至5 mm / h的生长速率获得Lu ₂ SiO ₅（LSO）晶体至共晶陶瓷棒。新获得的共晶是由Lu ₂ O _3的原纤维和/或薄片形成的LSO基体，是在LFZ生长期间由SiO ₂蒸发过程诱导形成的。

扫描电子显微镜（SEM）和拉曼光谱研究允许观察生长速率如何影响微观结构的演变，即从单晶到共晶的转变。SEM观察表明，共晶存在交替的单相含正硅酸盐的单相区域，双相Lu ₂ SiO ₅ / Lu ₂ O ₃通过X射线衍射鉴定为C2 / c单斜度Lu ₂ SiO ₅和Ia${\displaystyle \overline{3}}$ 立方氧化oxide。

虽然发现发光现象仅取决于激发能量，但是在以较低速率生长的样品中观察到明显的紫外线诱导的可逆光致变色效应。
