英文摘要We present new estimates of the luminosity function (LF) and star formation rate density (SFRD) for an H alpha-selected sample at z similar to 0.62 from the Deep And Wide Narrow-band (DAWN) survey. Our results are based on a new H alpha sample in the extended COSMOS region (compared to Coughlin et al.) with the inclusion of flanking fields, resulting in a total area coverage of similar to 1.5 deg(2). A total of 241 H alpha emitters were selected based on robust selection criteria using spectrophotometric redshifts and broadband color-color classification. Given that dust extinction is a dominant uncertainty in the estimation of LF and SFRD, we explore the effect of different dust-correction prescriptions by calculating the LF and SFRD using a constant dust extinction correction, A(H alpha) = 1 mag, a luminosity-dependent correction, and a stellar-mass-dependent correction. The resulting H alpha LFs are well fitted using Schechter functions with best-fit parameters: L* = 10(42.24) erg s(-1),
