The key issue for a wide application of solar energy is the possibility to establish an innovative photovoltaic technology that allows more efficient conversion. In this direction, use additional layers in well‐established silicon‐based modules represents challenging strategy. context, present work devoted optimization downshifting (DS) system made NaGdF 4 matrix form thin film as host material europium‐luminescent ions. Eu‐doped fabricated through sol–gel approach starting from mixture Na(hfa)•tetraglyme, Gd(hfa) 3 •diglyme, and Eu(hfa) •diglyme ethanol solution. operative parameters are finely tuned pursue formation compact polycrystalline films. Particularly, annealing treatment, nature substrate, doping ion percentage reproducible selective beta (hexagonal) crystal structure with promising luminescent properties. Morphological, structural, compositional features deeply studied field‐emission scanning electron microscopy, X‐ray diffraction analysis, energy‐dispersive respectively. luminescence investigations confirm properties DS system.
