With the LED commercial lighting, small and medium- size panel backlighting applications such as gradually extended , high-brightness LED market demand in recent years has been in a phase of rapid growth . Meanwhile , COB, integrated modular package rise of emerging market demand , driven phosphor market this year a substantial increase in overall sales .

LED Engineering Research Institute (GLII) latest survey data show that in 2013 China LED phosphor market volume growth is expected to exceed 60% , while the market growth will exceed 20%.

2013 Engineering LED encapsulation special meeting will be in Guangzhou Poly World Trade Center , Hall 5 Conference Room D hold , then the summer will Grirem engineer "LED Phosphor ' optical quality of the ' innovation ' keynote speech .

" Starting in 2008 , Grirem to SMD phosphor -based, covering high-power yellow phosphor , and began large-scale layout nitride red phosphor, and efficient development of these products , not only to break the foreign monopoly of the industry the rapid development has played a leading role. "In the summer , said earlier this year , the domestic packaging, applications generally reflect the significant recovery of the market , while the phosphor market began to pick up from March .

In fact, from 1966 reporting Nichia blue LED chip coated with yellow phosphor YAG start forming white patent , YAG yellow phosphor white LED has been the commercial mainstream technology program, but a low CRI allows a single bottleneck YAG Rhubarb program has not been able to meet the immediate requirements of the lighting market .

" High CRI white LED has become the inevitable trend of future development of a single YAG gluten transformation imperative . "Summer said that the current international companies as well as numerous domestic packaging manufacturers have gradually begun to try to use other color phosphors varieties, such as LuAG.

Pink nitrides which will play an increasingly important role. From a technical perspective , the current nitride Pink is a recognized system of practical value , but also affect the white LED indoor general lighting applications to expand one of the important factors , there is no doubt a very important market value and broad market space.

Summer said that after three years of hard work , in 2011 , Grirem domestic market share has been ranked highest in LED phosphor products already covered by yellow, green and red phosphors whole band , the main compound system as aluminate and nitride , yellow-green powder which ten balance aluminate and nitride pink ten balance in accordance with the relevant laws for effective combinations, fully able to meet the high color , high brightness white LED market demand.

Phosphorus bonding of transition metal-containing complexes of the theoretical development not only for bonding a significant contribution , and that such complexes in the field of synthetic chemistry have important practical applications . In the past few decades , a large variety of transition metal-containing complexes of phosphate bond is synthesized , and the phosphorous containing rare earth complexes bond is an exception. This is because the rare earth metal ion is a hard Lewis acid , and phosphorus is a soft Lewis base , according to Pearson's HSAB (HSAB) principle , rare earth phosphate bonding is matched. Before 2008 only about a dozen cases of rare earth phosphino complexes , no phosphine carbene complexes of rare earth road, but only in rare earth metal phosphide is an inorganic solid form ionic bonds (LnP) exists.

Chinese Academy of Sciences Shanghai Institute of Organic Chemistry State Key Laboratory of Organometallic Chen Yaofeng research group carried out a rare earth phosphate bonding work , research into rare earth metal ions and phosphorus key mode . In 2008, the Task Force and the U.S. Los Alamos National Laboratory Kiplinger research group reported the a light rare earth (Nd) and a heavy rare earth (Lu) bridging phosphine carbene complexes . They then synthesized the first soluble rare earth metal phosphide , and characterized by solution NMR and single crystal X-ray diffraction characterization . This work is of rare earth metals and soft Lewis bases ligand bonding a breakthrough , rich rare earth metal complexes of the structural system and bonding mode.

Recently, they use the Task Force developed tridentate nitrogen ligand synthesis of rare earth scandium bridged phosphine carbene complexes . Found rare scandium phosphine carbene complexes bridged only by PP coupling of a reducing agent 2e bipyridine , triphenyl phosphine sulfide and selenium phosphine, a series of unsaturated addition reaction of the substrate can even activated carbon monoxide (CO) and metal carbonyl compounds , resulting oxygen CC bond and triple bond coupling rupture of generating novel phosphine compound. This work has revealed a rare earth - phosphate bond does not match the reactivity brought novel .

The work from the National Natural Science Fund Committee , Ministry of Science , Chinese Academy of Sciences and the Shanghai Municipal Science and Technology Commission funding.
