Organic single crystals have excellent transport and unique optical properties, which are very advantageous to light-emitting devices. However, it is still difficult to control the emitting color of these devices and we need to establish a novel method to introduce a color-control system into organic single crystals. In this paper, we present an effective approach for the fabrication of submicrometer-scale grating structures on an organic singlecrystal surface. Using the UV-nanoimprint lithography and dry-etching methods, one-dimensional grating structures are fabricated on crystal surfaces and, from photoluminescence spectra, we confirmed the color tunability of this novel method.
