Luminescent perovskites: From materials to light-emitting devices

2019

The thesis describes the preparation of efficient and simple bright halide perovskite materials and light-emitting devices. In the different chapters, several perovskite types are described and studied: Perovskites with different crystal sizes, from nanosized perovskites (Chapter 2, 3 and 4) to bulk perovskites (Chapter 5) all with a 3D crystal structure; and perovskites with different crystal structure dimensionalities, such as 3D or nanoplatelets with 2D (Chapter 3) and even quasi-2D structures (Chapter 2). Photoluminescence and electroluminescence with colours ranging from red to green and blue are reported. Chapter 2 focuses on obtaining stable and very PL efficient red-emitting hybrid …
