Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The article delves into the challenges and solutions for improving the stability and performance of quantum-dot light emitting diodes (QLEDs) using PEDOT:PSS as a hole injection layer. It discusses the inherent disadvantages of PEDOT:PSS and the strategies employed to enhance its properties, focusing on the use of urea and IPA treatments to improve conductivity and surface morphology. The study shows that these treatments significantly enhance the efficiency and stability of QLEDs, offering a promising pathway for commercializing this advanced technology. The research provides a comprehensive analysis of the surface morphology and electro-optical properties of QLEDs, demonstrating the effectiveness of the modified PEDOT:PSS films in achieving high luminance and efficiency. The findings are supported by detailed experimental results, including current density-voltage-luminance characteristics and electroluminescence spectra, making the article a valuable resource for researchers and professionals in the field.
