摘要： Provided is a photo-luminescence (PL) LCD including: electrodes that are disposed on bottom and top surfaces of front and rear substrate and create an electric field in liquid crystals (LCs); a nano-dot (ND) PL layer that is disposed on the bottom surface of the front substrate and emits light when irradiated with ultraviolet (UV) light, and a UV backlight unit that is located behind the rear substrate and supplying UV light to the ND PL layer. The UV backlight unit is excited by blue UV light having a wavelength range of 360 to 460 nm to emit light. The PD LCD having the above-mentioned structure suppresses absorption of UV light by LC and degradation of the LC while providing high light efficiency.

摘要： A method for preparing nanocrystal-metal oxide composites with long-term stability is disclosed herein. The nanocrystals are mixed with a first metal oxide precursor, a solvent and water to form a sol-gel composite. The sol-gel composite is pulverized to form a sol-gel composite powder. The sol-gel composite is then reacted with a second metal oxide precursor. The nanocrystal-metal oxide composites have a high luminescence efficiency and uniform emission wavelengths. The nanocrystal-metal oxide composite is used to manufacture a light-emitting device.
