Plant‐Based Structures as an Opportunity to Engineer Optical Functions in Next‐Generation Light Management

“…Luminescence is a spontaneous, non-thermal process, in which light is emitted by luminescent materials (or phosphors) in the spectral region of ultraviolet, visible, or infrared. [145] This process may occur due to chemical reactions (chemiluminescence), [146][147][148][149] electrical energy (electroluminescence), [150] mechanical stressors (mechanoluminescence), [151,152] or the absorption of photons (photoluminescence). [153] In this section, we will focus on reviewing the photoluminescence of lignocellulosic materials, because only few studies have been reported on the other types of luminescence in the past five years.…”

Fabrication and biocompatibility analysis of flexible organic light emitting diodes on poly(lactic acid) substrates: toward the development of greener bio‐electronic devices

“…Additionally, solid state lighting devices in particular show multiple applications in the field of photodynamic therapy, optogenetic, sensing, as well as wearable displays 10 . A very promising solid‐state lighting technology is represented by the organic light emitting diode (OLED) one, since it combines excellent properties in terms of luminous efficiency and intrinsic characteristics of organic materials 4,11,12 . Organic materials are soft, flexible, and often biocompatible and hence they can be properly exploited for the design of bio‐optoelectronic devices.…”

Moreover, currently the commercially available luminescent organic materials are characterized by different emission spectra such to cover almost the entire visible wavelength range.…”

Designing Artificial Fluorescent Proteins: Squaraine‐LmrR Biophosphors for High Performance Deep‐Red Biohybrid Light‐Emitting Diodes

“…[7,8] In this scenario, hybrid LEDs (HLEDs) have been reborn, promising to achieve sustainable lighting systems without losses in device performance. [9][10][11][12][13][14] They aim at replacing IPs with organic color down-converting filters or organic phosphors (OPs) that combine organic emitters (e.g., small molecules, coordination complexes, polymers, or carbon dots, among others) with polymers, metallic organic frameworks (MOFs), etc., as packaging matrices. [15][16][17][18][19][20][21][22][23] Though this field started at the beginning of the 21 st century, several recent advances have set in their relevance.…”
