Evaluation of photoluminescence quantum yield of monolayer WSe2 using reference dye of 3-borylbithiophene derivative
We studied an evaluation method of photoluminescence (PL) quantum yield of monolayer transition metal chalcogenides (TMDs) on a transparent substrate using a reference dye. A 3-borylbithiophene derivative (C58H49BN2S4) reference dye shows a high PL quantum yield of 36% even in the solid form and the...
