Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Safety of (4-Chlorophenyl)methanol, 873-76-7, Name is (4-Chlorophenyl)methanol, molecular formula is C7H7ClO, belongs to alcohols-buliding-blocks compound.

Functional applications and luminescence properties of emission tunable phosphors CaMoO4@SiO2:Ln(3+) (Ln=Eu, Tb, Dy)
In this present work, a room temperature coprecipitation method for the synthesis of CaMoO4@SiO2:Ln (Eu3+, Tb3+, Dy3+) phosphors was reported. These particles were characterized using X-ray diffraction (XRD), Energy dispersive spectrometer (EDS), Fourier Transform IR spectroscopy (FTIR), scanning electron microscope (SEM), UV-visible spectrophotometer and photoluminescence (PL) respectively. The results indicated that emission intensity of SiO2 modified samples increased by about 2 times, compared with no-silica modified samples. Multicolor phosphors were also designed by changing the lattice activators (Eu3+, Tb3+, Dy3+). To further explore its applications, the transparent photoluminescent film was developed through the incorporation of polyvinyl alcohol (PVA), and selective and sensitive detection performance on dichromate was demonstrated in detail. In addition, red emission LED devices was assembled with as-prepared phosphors. The present results provide not only the high-performance phosphors modified by silica, but also a deep explanation of the structure-property relationship of the as-prepared sample. Based on these findings, it can be foreseen that these microparticles will be applied in versatile filed. (C) 2020 Elsevier B.V. All rights reserved.
