Tm-doped (Sc0.5Y0.5)2SiO5 (SYSO) crystals were grown by Czochralski method. The UV-VIR-NIR absorption spectra and the near-infrared emission spectra were measured and analysed by the Judd-Ofelt approach. Temperature influence on both absorption and e

The present paper investigates steady eutectic growth with the isotropic surface tension by using the analytical approach. We consider the case that Peclet number ϵ is small and the segregation coefficient κ is close to the unit, and obtain a famil

The present paper is concerned with the global instability mechanisms for the basic steady state of lamellar eutectic growth with curved and tilted interface affected by the triple point. We solve the related linear eigenvalue problem (EVP) by using

We study the effect of anisotropic surface tension on the interface evolution of a particle growing in the undercooled melt by using the matched asymptotic expansion method. The analytical results show that immediately after the nucleation at the ini

Crystals of Ce 3+ -doped (Lu x Y 1− x ) 3 Al 5 O 12 (LuYAG) have been grown and studied by X-ray powder diffraction, emission spectroscopy, excitation spectroscopy and X-ray excited fluorescence spectroscopy. The X-ray powder diffraction pattern re

Blue-light emission at room temperature was observed in SrTiO 3 film with SrRuO 3 as buffer layer on LaAlO 3 substrate. Other SrTiO 3 films, such as grown directly on LaAlO 3 and GaAs substrate or with DyScO 3 as buffer layer on LaAlO 3 , which all h

The present paper investigates the global instability mechanisms of arrayed-cellular growth with asymptotic approach. We find that the system involves two types of global instability mechanisms: the low frequency (LF) instability and the global oscil

The morphologies and crystallographic orientations of quench-textured olivine, diopside and plagioclase, artificially crystallized at cooling rates of 3-5 °C min ―1 , have been investigated by scanning electron microscopy (SEM) and Electron backsc
