This study enhanced the light extraction efficiency ( of a remote phosphor white LED by using a hemiellipsoidal antireflection subwavelength structure (ASS) polyethylene terephthalate (PET) film. T he PET film was fabricated and combined with a hemiellipsoidal ASS on the surface of a remote phosphor white LED through a UV curing adhesive process. The improvements in the LEE of the remote phosphor white LED with an ASS PET film are 1 1. 76 % and 23.26% c ompared with the remote phosphor white LED and conventional phosphor converted white LED..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
