Nd-Sialon microcrystals with a novel orthogonal array morphology were developed by inducing catalysis of Fe for the first time, via a combination of vapor−liquid−solid (VLS) and vapor−solid (VS) growth mechanisms. The chemical composition of Nd-Sialon crystals was determined to be NdSi_5.4Al_1.6O_0.6N_9.4. The morphology of the tips strongly depended on the relative position of the liquid droplet to the crystal. Furthermore, the crystal growth process of Nd-Sialon microcrystals with the novel morphology was discussed. The Nd-Sialon single crystal shows UV-to-blue emission when it is excited by a wavelength of 325 nm. Nd-Sialon is envisioned to have potential in many functional applications, such as white LEDs, detector arrays, MEMS, and optical components. This work shines a light on the growth of Nd-Sialon single crystals for potential laser application.
