Colour tuning in white hybrid inorganic/organic light-emitting diodes

Implementing fluorescent MOFs as down-converting layers in hybrid light-emitting diodes

“…7 Previously we have demonstrated a series of organic donor-acceptor molecular species that act as light-converting layers on top of inorganic InGaN-based LEDs. [8][9][10] We disclosed a blue-absorbing molecular colourconverter that incorporated an electron-deficient tetrafluorobenzene core into the fluorene-BODIPY scaffold. This molecule was designed to absorb in the blue and emit yellow light, providing an overall white emission when deposited on top of a blue LED.…”

A poly(urethane)-encapsulated benzo[2,3-d:6,7-d′]diimidazole organic down-converter for green hybrid LEDs

“…More recently, a hybrid device with improved luminous efficacy and colour rendering was achieved through the use of a benzothiadiazolebased material as the down-converting layer. 12 We have also shown the potential for metal-organic frameworks (MOFs) to be used as the down-conversion layer when embedded within a suitable encapsulating material. 13 Such a strategy rigidifies the down-converting material counteracting aggregation and luminescence quenching.…”

Versatile Homoleptic Naphthyl‐Acetylide Heteronuclear [Pt2M4(CC‐Np)8] (M = Ag, Cu) Phosphors for Highly Efficient White and NIR Hybrid Light‐Emitting Diodes

“…Therefore, renewed interest has emerged in OPs, leading to hybrid LEDs (HLEDs) . This involves Cd‐based quantum dots (Cd‐QDs), ionic transition metal complexes, fluorescent proteins, organic small molecules, molecular organic frameworks (MOFs), and perovskites . In general, HLEDs have achieved efficiencies up to 130 lm W −1 and a high color quality with x / y International Commission on Illumination (CIE) color coordinates of 0.30‐3/0.30‐3, CRI above 90, and easy‐to‐modulate CCT from 2700 to 6500 K .…”
