Dataset of Ligand-Controlled Synthesis of CsPbBr3 Nanoplatelets

The data saved in the folder name of Figure2 are related to the photoluminescent emission spectra recorded after 365 nm excitation for cesium lead bromide nanoplatelets at ligand concentration of x = 1 with different ligand chain length from butylamine (C4) to oleylamine (C18) and at different ligand concentration of x =0.5 - 2 using fixed octylamine (C8) as a ligand. The data save in the folder name of Figure5 are related to the photoluminescent emission spectra recorded during the process of halide exchange using CsPbBr3 nanoplatelets as a parent starting compound with adding PbCl2 or PbI2 to control the bandgap.图2对应文件夹中存储的数据，为溴化铯铅纳米片在365纳米激发下测得的光致发光发射光谱相关数据：其一为配体浓度x=1、配体链长从丁胺（C4）到油胺（C18）不等的样品光谱；其二为以固定辛胺（C8）作为配体、配体浓度为0.5~2时测得的同类光谱数据。 图5对应文件夹中存储的数据，是以CsPbBr3纳米片作为起始前驱体，通过添加氯化铅（PbCl2）或碘化铅（PbI2）调控带隙过程中测得的光致发光发射光谱相关数据。
