Embodiments of the invention may allow a sample suspected of containing an explosive (e.g., a peroxide) or other species to interact with a reactant, wherein the sample may react and cause light emission from the reactant. Advantages of the present invention may include the simplification of devices for determination of peroxide-based explosives, wherein the devices are portable and, in some cases, disposable. Other advantages may include relative ease of fabrication and operation. ## Claims ### Claim 1 A device for determining a vapor phase peroxide or a vapor phase peroxide precursor, comprising: an inlet for intake of a vapor sample suspected of containing the vapor phase peroxide or vapor phase peroxide precursor; a sample cell comprising a composition comprising a peroxide-reactive material, a light-emitting material, and a support material, wherein the peroxide-reactive material and the light-emitting material are different, and wherein the composition is in solid form, or, the composition is in solution form and the support material is a liquid having a boiling point of at least 300° C., the sample cell constructed and arranged to receive the vapor sample; and a detection mechanism in optical communication with the sample cell, wherein the peroxide-reactive material is a compound having the formula, wherein R′ is a group comprising a sulfonyl and R″ is 2,4,5-trichlorophenyl, 2,3,4,5,6-pentafluorophenyl, 2,4-dinitrophenyl, phenyl, or a substituted derivative of any of these, and the light-emitting material is a compound having the formula, wherein R is alkyl, heteroalkyl, aryl, or heteroaryl. ### Claim 2 (depends on 1) The device of claim 1, wherein the composition is in solid form and the peroxide-reactive material and the light-emitting material are supported on the support material. ### Claim 3 (depends on 1) The device of claim 1, wherein the peroxide-reactive material, the light-emitting material, and the support material form a solution. ### Claim 4 (depends on 1) The device of claim 1, further comprising a catalyst selected from the group consisting of a carboxylic acid with a pKa value between 1-6 in neat water and a phenol with a pKa value between 1-6 in neat water. ### Claim 5 (depends on 1) The device of claim 1, wherein the light-emitting material has an emission spectrum between 400-700 nm. ### Claim 6 (depends on 1) The device of claim 1, wherein the light-emitting material is covalently bonded to the peroxide-reactive material. ### Claim 7 (depends on 1) The device of claim 1, wherein the support material is in solid form and the light-emitting material is covalently bonded to the support material. ### Claim 8 (depends on 1) The device of claim 1, wherein the support material is in solid form, comprising corn starch. ### Claim 9 (depends on 1) The device of claim 1, wherein the support material is in solid form, comprising a gel. ### Claim 10 (depends on 1) The device of claim 1, wherein the support material is in solid form, comprising a solid absorbent material. ### Claim 11 (depends on 1) The device of claim 1, wherein the support material is in solid form and may be molded into a shape. ### Claim 12 (depends on 11) The device of claim 11, wherein the shape is a film, bottle, sphere, tube, strip, or tape. ### Claim 13 (depends on 1) The device of claim 1, wherein the support material is in solid form, comprising silica. ### Claim 14 (depends on 1) The device of claim 1, further comprising a buffer. ### Claim 15 (depends on 1) The device of claim 1, wherein, in the presence of a peroxide, the light-emitting material has a quantum yield of at least 50%. ### Claim 16 (depends on 1) The device of claim 1, wherein, in the presence of a peroxide, the light-emitting material has a quantum yield of at least 75%. ### Claim 17 (depends on 1) The device of claim 1, wherein, in the presence of a peroxide, the light-emitting material has a quantum yield of at least 90%. ### Claim 18 (depends on 1) The device of claim 1, wherein, in the presence of a peroxide, the light-emitting material has a quantum yield of at least 99%.
