Abstract information

English title:	Development of perovskite biopolymeric film with photoluminescent properties
Spanish title:	Desarrollo de pel�culas biopolimericas de perovskita con propiedades fotoluminicentes
English abstract:	Energy-efficient materials, such as perovskites, have attracted attention due to their characteristics, low costs, and variety of production methods, allowing them to be used in optoelectronic devices. However, they become unstable when exposed to air, humidity, or temperatures, so structures with sustainable materials are explored to maintain their durability, optimize their fabrication, and costs. Hence, it is proposed to synthesize perovskites 〖CsPbBr〗_3 in a biopolymeric matrix, which promotes the use of hydrocarbon-free polymers. The implemented polysaccharides are from potato and invasive aquatic plants of Lake Tota (Elodea), and were dissolved with the precursors (lead acetate and cesium bromide) in dimethyl sulfoxide and dimethylformamide under ambient conditions. Finally, different techniques were used to study the optical, morphological, and structural properties of the material, confirming its application feasibility by obtaining homogeneous, photoluminescent films and a process where the starches behaved as organic ligands for the formation of perovskite.

Sin embargo, se vuelven inestables cuando se exponen al aire, la humedad o las temperaturas, por lo que se exploran estructuras con materiales sostenibles para mantener su durabilidad, optimizar su fabricaci�n y costes. Por ello, se propone sintetizar perovskitas 〖CsPbBr〗_3 en una matriz biopolim�rica, lo que favorece el uso de pol�meros libres de hidrocarburos. Los polisac�ridos implementados provienen de la patata y de plantas acu�ticas invasoras del lago Tota (Elodea), y se disolvieron con los precursores (acetato de plomo y bromuro de cesio) en dimetilsulf�xido y dimetilformamida en condiciones ambientales. Finalmente, se utilizaron diferentes t�cnicas para estudiar las propiedades �pticas, morfol�gicas y estructurales del material, confirmando su viabilidad de aplicaci�n mediante la obtenci�n de pel�culas fotoluminiscentes homog�neas y un proceso en el que los almidones se comportaron como ligandos org�nicos para la formaci�n de perovskitas.
