With the use of two light emitting devices 302, 303, the amount of pump light is advantageously doubled.

使用两个发光装置302、303，有利地使泵浦光的量加倍。

If its energy is larger, it may impart energy to atomic electrons as described by the Bohr theory, causing excitation of electrons to higher energy states or producing ionization, with subsequent emission of light.

果其能量更大，它可以按照波尔理论把能量传递给原子的电子，使电子激发到高能态或电离，并伴随发光现象。

With the decrease of the coplanarity of thiophene derivatives or its feed ratio, the PL and EL spectra can be blue shifted.

通过增加发光中心结构的空间位阻来减小其共轭程度，可以使聚合物的PL和EL光谱发生较大蓝移。

The resulting materials were characterized by x-ray diffraction, Fourier transform infrared spectroscopy, Nuclear magnetic resonance and Photoluminescence. Those spectra reveal that by adding SiO2 to YAG:Ce precursor, the lattice constant decreases while vacancies are generate due to the co-dopant ions (Si4+) replaces in the place of Al3+ sites of YAG:Ce system. YAG:Ce phosphors with Y3+ dodecahedral site replaced by Ce3+ and diffused effectively as an activator, as a result the photoluminescence intensity increased about ~20-30%.

研究成果显示，掺杂SiO2之YAG：Ce萤光粉经过高温热处理后，由X光绕射、红外线吸收光谱仪以及核磁共振可以得知，当SiO2添加量增加时，YAG：Ce晶格常数会因为Si4+取代Al3+的四面体晶格位置而变小，同时产生将YAG：Ce之铝离子空位缺陷，使活化中心更有效地在YAG：Ce主体中扩散取代Y3+的十二面体晶格位置，提高其发光性质约20~35%。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
