Exploring calibration-free luminescence thermometry with Mn 4+ anti-Stokes/Stokes emission

Mn 4+ -activated phosphors offer a unique possibility of calibration-free primary luminescence thermometry using the ratio of anti-Stokes to Stokes (AS/S) vibronic emission lines of the 2 E → 4 A 2 transition. Previous work used the AS/S emission of Mn 4+ for thermometry but alwa...

Cation‐Engineered Narrow‐Band Green Emitting Phosphor Toward High‐Performance Laser‐Driven Displays

ABSTRACT Wide color gamut and high brightness are critical performance metrics for advanced displays like projectors. Combining narrow‐band green and red color converters with a blue laser‐driven light source is one of the most effective solutions to achieve these goals. In this...
