摘要：

Hexagonal boron nitride (h-BN) is being widely utilized as a platform for optical and electrical devices exploiting two-dimensional layered materials. By analyzing transmission spectra of h-BN flakes transferred onto quartz plates with the transfer-matrix method, the refractive index of h-BN is determined in the wavelength range from 450 to 1200 nm. The transmission spectra are reproduced by applying the single oscillator model of n(lambda)(2) = 1 + A lambda(2)/(lambda(2)-lambda(2)(0)) as the wavelength-dependent refractive index. Averaging over the parameters from different samples, the parameters of lambda(0) = 164.4 nm and A = 3.263 are obtained.
