Study on the Management Quality of China Woman Enterprisers

China women have formed their special personalities and characters different from men＇s. Enterprisers, who can prove equal to the task, must possess the management qualities. Women engaged in management work also need to possess the same management qualities. This paper discusses the advantages and disadvantages and help China women become excellent enterprisers. Management quality is a based condition possessed in management work, which includes the education degree, the level of some knowledge, the function of psychology, the skill, the experience, the health and so on. One of the important specific properties of management quality is the difference. The management qualities are connected with the management behaviors and performances. The advantages of the women enterprisers＇ management qualities are on three parts such as their vocational interests, values and personalities. The disadvantages are their psychological minds of their inferiority, dependency and mediocrity.

Fine-grained phosphors for red-emitting mini-LEDs with high efficiency and super-luminance

Mini-LED backlights,combining color conversion materials with blue mini-LED chips,promise traditional liquid crystal displays(LCDs)with higher luminance,better contrast,and a wider color gamut.However,as color conversion materials,quantum dots(QDs)are toxic and unstable,whereas commercially available inorganic phosphors are too big in size to combine with small mini-LED chips and also have strong size-dependence of quantum efficiency(QE)and reliability.In this work,we prepare fine-grained Sr_(2)Si_(5)N_(8):Eu^(2+)-based red phosphors with high efficiency and stability by treating commercially available phosphors with ball milling,centrifuging,and acid washing.The particle size of phosphors can be easily controlled by milling speed,and the phosphors with a size varying from 3.5 to 0.7 mm are thus obtained.The samples remain the same QE as the original ones(~80%)even when their particle size is reduced to 3.2-3.5 mm,because they contain fewer surface suspension bond defects.More importantly,SrBaSi_(5)N_(8):Eu^(2+)phosphors show a size-independent thermal quenching behavior and a zero thermal degradation.We demonstrate that red-emitting mini-LEDs can be fabricated by combining the SrBaSi_(5)N_(8):Eu^(2+)red phosphor(3.5 mm in size)with blue mini-LED chips,which show a high external quantum efficiency(EQE)of above 31%and a super-high luminance of 34.3 Mnits.It indicates that fine and high efficiency phosphors can be obtained by the proposed method in this work,and they have great potentials for use in mini-LED displays.
