Efficient and spectrally stable pure blue light‐emitting diodes enabled by phosphonate passivated CsPbBr3 nanoplatelets with conjugated polyelectrolyte‐based energy transfer layer

EcoMat
Lead halide perovskites exhibit a very wide color gamut due to their extremely narrow emission spectra, typically characterized by a full‐width at half‐maximum (FWHM) of less than 20 nm.

Water-Stable Perovskite Quantum Dots for Wide-Color-Gamut White-Light-Emitting Diodes

Photonics
Perovskite quantum dots (PQDs) based on CsPbX3 (X = Cl, Br, I) have attracted extensive attention due to their outstanding optoelectronic properties; however, their practical applications are hindered by poor environmental stability.

Estimation of the device gamut of a digital camera in raw performance using optimal color-stimuli

, 2003
Using a spectroradiometric model of capture for a digital camera based on the mathematical description of the empirical opto-electronic conversion spectral functions (OECSF), the capture of MacAdam or optimal spectra with fixed illumination level is simulated.
