^a 40 wt % heterogeneous POSS and mixture with 20 wt % each POSS. ^b Determined with the peak at 407 nm. ^c Determined with the peak at 509 nm (λ_ex = 407 nm). ^d Compared with 41% from the pristine polymer. ^e Determined as an absolute value with the integration sphere method. ^f Determined with the peak at 484 nm. ^g Determined with the peak at 639 nm (λ_ex = 484 nm). ^h Determined with 0.7% from the pristine polymer.
