The full metal microcavity with the structure of Glass/Ag(30 nm)/Alq(120 nm)/Ag(30 nm) is fabricated.Angular dependence of the emission spectra and their full width at half maximum(FWHM) values between 0° and 60° are investigated.When changing the diverge angle from 0° to 60°,the resonance wavelength and their FWHM values change from 585.8 nm to 546.6 nm and from 26.8 nm to 36.6 nm respectively.The reasons of the blue shift and broadening of spectrum with increasing of the diverge angle are anal...
