Abstract

Thermolytic decomposition of N [triple bond, length as m-dash] Mo(O^tBu)₃ with Ti(O^tBu)₄ results in mixed-metal oxynitrides that retain 75% of the N from the nitrido precursor. The fundamental photophysics of the oxynitrides were investigated, and TRMC measurements determined that Mo and N are critical to the long charge carrier lifetimes in the microsecond regime.
