Abstract

A multi-photon reactive composition including: (a) at least one reactive species; and (b) multi-photon photoinitiator system; and (c) a plurality of substantially inorganic particles, wherein the particles have an average particle size of less than about 10 microns in diameter.

1 . An article comprising: 
 (b) an at least partially reacted species; (b) a multi-photon photoinitiator system; and    (c) a plurality of substantially inorganic particles,    wherein the particles have an average particle size of less than about 10 microns in diameter, and said particles are present in the composition at up to about 65% by volume.    
   
   
       2 . The article of  claim 1 , wherein the reacted species is selected from the group consisting of acrylates, methacrylates, styrenes, epoxies, vinyl ethers, cyanate esters, and mixtures thereof.  
   
   
       3 . A method for making an organic-inorganic composite comprising: 
 (a) providing a multi-photon reactive composition comprising: 
 (1) a reactive species,  
 (2) a multi-photon photoinitiator system,  
 (3) and a plurality of substantially inorganic particles,  
 wherein the particles have an average particle size of less than about 10 microns in diameter;  
   (b) irradiating the multi-photon reactive composition with sufficient light to at least partially react the composition; and    (c) removing a soluble portion of the multi-photon reactive composition from the resulting composite.    
   
   
       4 . The method of  claim 3 , further comprising subjecting the composite to a sufficiently elevated temperature for a sufficient amount of time to pyrolyze the reactive species and to at least partially fuse the particles.  
   
   
       5 . The method of  claim 4 , wherein the composite is heated to a temperature of between about 500° C. to about 1400° C. for about 2 hour to about 48 hours.  
   
   
       6 . The method of  claim 4 , wherein the doping agent is selected from the group consisting of metal salts, fluxing agent, dyes, sol-gel precursors, organometallic precursors, and combinations thereof.  
   
   
       7 . The method of  claim 4 , wherein the fluxing agent comprises boron oxide, boric acid, borax, and sodium phosphate.  
   
   
       8 . The method of  claim 4 , further comprising the step of sintering the structure for a time and temperature sufficient to achieve a substantially consolidated inorganic structure.
