An organic luminescent material includes a host luminescent material and a guest luminescent material. The host luminescent material includes a compound represented by formula (1), where n is 0&#x2dc;8; Rand Rrespectively represent H, CF, CN, CHor CH; Ris CHor one of substituents shown as follows: 

Organic luminescent material and organic electroluminescent apparatus

A white color light source of an organic light emitting diode is provided and is suitable for irradiating on plants. The white color light source includes a first color light and a second color light. A peak in the frequency spectrum of the first color light is within a first wavelength range. A peak in the frequency spectrum of the second color light is within a second wavelength range. The white color light source is at least formed by mixing the first color light and the second color light, wherein an intensity of a frequency spectrum of a wavelength range from 520 nm to 580 nm is substantially equal to or less than 20% of a total intensity of a frequency spectrum of the white color light source.

White color light of organic light emitting diode

In one aspect of the invention, an organic light emitting diode device has a substrate, a cathode formed on the substrate, an anode spaced-apart from the cathode, a plurality of electroluminescent units stacked between the cathode and the anode, and a plurality of charge generation layers, each of which is formed between two adjacent electroluminescent units. Each electroluminescent unit has an electron-transport layer, an emission layer formed on the electron-transport layer, and a hole-transport layer formed on the emission layer. The electron-transport layer of the first electroluminescent unit is formed on the cathode, defining a first energy barrier, and the anode is formed on the hole-transport layer of the last electroluminescent unit, defining a second energy barrier. The first energy barrier is higher than the second energy barrier. The first electroluminescent unit has a lifetime longer than that of each of the rest electroluminescent units.
