| abstract | We demonstrate an improvement of the emission quantum yield and the luminance figures of merit of metal-free bridged silsesquioxanes-by a factor of 2, 0.43 +/- 0.04, and by two orders of magnitude, (1.4 +/- 0.1) x 10 4 cd m(-2), respectively-by changing the regioisomer of the silylated precursor. The organic-inorganic hybrids are easily excited by commercial blue InGaN-based light emitting diodes (LEDs) displaying an intriguing potential to applications in green photonics as metal-free phosphors for solid state lighting. |
