英文摘要	A novel route to modify the luminescent performances of Ce:YAG phosphor-in-glass (PiG) film is proposed in this work, where the yellow-emitting PiG film was placed on regularly nanoscale textured glass substrate through spin coating technique. Different from the mechanical scraping, the regularly textured surface substrate is successfully obtained using hydrofluoric acid solution (HF 48–51%) by chemical wet-etching method and the roughness can be modified by adjusting synthesis time. The textured glass substrate can not only improve the optical uniformity and enhance luminous efficacy by minimizing total internal reflection (TIR), but reinforce the diffuse reflection light to improve visual comfort. The research results show that the quantum yield (QY) and luminous efficacy of the film based w-LEDs on textured glass substrate increase by 22.9% and 11.18%, respectively. These results may bring an inspiring insight to prepare remote phosphor with different spectral performance on regularly textured surface for remote white LEDs. © 2018 Elsevier Ltd and Techna Group S.r.l.
